Factoring Worksheets for Grade 5

Factoring is a type of mathematical exercise where we break a number into smaller parts, and when calculating those parts, we need the same number as an answer. This worksheet will help kids to understand the basics of factoring and how factors can be represented. Below, we have introduced different factoring exercises that will improve kids’ problem-solving skills and boost their confidence in math. To handle all the exercises below, kids need to be attentive and energetic.

Factoring Numbers Under 100 Worksheet For Grade 5

1. 8 ->1, 2, 4, 8 2. 11 -> 1, 11 3. 20 ->1, 2, 4, 5, 10, 20 4. 39 -> 1, 3, 13, 39 5. 43 -> 1, 43 6 . 59 ->1, 59 7. 77 -> 1, 7, 11, 77 8. 93 ->1, 3, 31, 93. In this exercise, kids need to find the factors of each number. Above, there are a total of eight exercises that kids need to perform. To solve this exercise, kids need to follow some rules. First, we have to break a number into smaller parts and remember that it is important to get the same number when we are calculating the parts again; otherwise, our answer will be incorrect.  Let’s take an example: 8. As per the rule, the factors will be 1, 2, 4, 8. You can check if the factor is correct or not by multiplying all the parts: 1 x 8 = 8, 2 x 4 = 8, 4x 2 = 8, 8x 1 = 8.

Solving exercises again and again will boost kids’ confidence to handle more complex problems. We believe that the kids have completed the above task, and now they are ready to handle this exercise. In this exercise, the number range is a little bit higher, but we want kids to take this exercise as a challenge and want them to perform it alone. We always want kids to move forward in their future without any help, so we assume kids will also handle this exercise.

Prime Factor Tree Worksheets For Grade 5

A prime factor tree is a simple graph that is used to represent the factors of a number. This process is simple and easy to understand. Above, we have a total of four prime trees, and there are four empty circles in which we need to write the factorials. This exercise will help kids understand the graph value and why the graph is important. We would be very glad if kids performed this exercise on their own. It is a simple exercise, and it helps them to understand graphs and improve their problem-solving skills.  

Divisibility Rules Math Worksheet For Grade 5

1.  2 -> Rules: The last digit in the number is even. Example: 4.8 Last digit is 8 (even). 2. 3 ->The sum of the digits of the number is divisible by 3. Example: 123+1+2+3=6, and 6 is divisible by 3. 3. 4 ->The number formed by the last 2 digits is divisible by 4. Example: 3.12 Last two digits are 12, and 12 is divisible by 4. 4. 5-> A number is divisible by 5 if the number formed by its last two digits is 0 or 5. Example: 75-Last digit is 5, so 75 is divisible by 5. 5. 6-> A number is divisible by 6 if it is divisible by both 2 and 3. Example: 24 -Last digit is 4 (even) & 2+4=6 (divisible by 3).  6. 9 ->The sum of the digits of the number is divisible by 9. Example: 7297+2+918, and 18 is divisible by 9. 7. 10-> A number is divisible by 10 if its last digit is 0. Example: 130 – Last digit is 0, so 130 is divisible by 10.
In this exercise, first, kids need to write the divisibility rules above in the table, and as per the rule, they need to solve the above table. Kids need to check whether the number is divisible or not. If yes, then make a correct sign; if no, then mark the wrong sign. So we hope kids have understood our exercise, and they will handle it on their own. Solving exercises will boost their confidence to handle more complex problems.

Greatest Common Factor 1 to 50 Worksheets For Grade 5

1. 4 -> 1, 2, 4. 8 -> 1, 2, 4, 8  GCF – 4
2. 12 -> 1, 2, 3, 4, 6, 12 20 -> 1, 2, 4, 5, 10,20 GCF – 4
3. 21 -> 1, 3,  7,  21 3 -> 1, 3 GCF – 3
4. 36 -> 1, 2, 3, 4,  6, 9, 12, 18, 36 9 ->1, 3, 9 GCF – 9
5. 30 -> 1, 2,3, 5, 6, 10, 15, 30 10 -> 1, 2, 5, 10 GCF – 10

In this exercise, we have introduced GCF, which stands for the greatest common factor. To solve this exercise, first, kids need to find out the factors of both given numbers and then check which number is common to both factors. It is a simple, common number-finding exercise; we want kids to perform this exercise. It will help them to find out common numbers and also help them to improve their number sense.

Greatest Common Factor 1 to 100 Worksheets For Grade 5

1. 20 -> 1, 2, 4 5 10 20 30 -> 1, 2, 3, 5, 6, 10, 15, 30   GCF – 10
2. 56 -> 1, 2, 4, 7, 8, 14, 28, 56 21-> 1, 3, 7, 21 GCF – 7
3. 36-> 1, 2,  3,  4, 6,9, 12, 18, 36 75-> 1, 3, 5, 15, 25, 75 GCF – 3
4. 57-> 1, 3, 19, 57 99 ->1, 3, 9,11,33, 99 GCF – 3
5. 86 -> 1, 2, 43, 86 2 -> 1, 2 GCF – 2

  This is the same exercise that we have done above, but here the numbers are a little bit higher. But we believe that if the process is known, you can solve even more complex exercises. We always motivate kids to not depend on anyone and also boost their confidence to handle math equations without any help. So we hope kids will solve this query independently. If they are facing issues, they can see the above-solved examples.

Least Common Multiple 2 to 30 Worksheets For Grade 5

1. 2 -> 2,4 4  -> 4  LCM- 4
2. 4 -> 4, 8 8 -> 8 LCM- 8
3. 5 -> 5, 10, 15, 20, 25 25-> 25 LCM- 25

5. 7 ->7, 14, 21, 28, 35, 42, 6 -> 6, 12, 18, 24, 30, 36, 42, LCM – 42

  In this exercise, we have introduced another concept, which is LCM. The least common multiple is nothing but the smallest number that can be a multiple of two or more. Above, we have a total of five queries, and for each, we need to find out the common number.  We hope this exercise will help kids understand the concept of LCM. We feel very happy if kids solve this on their own.

GCF & LCM Word Problem Worksheets For Grade 5

1. Lily visits the library every 6 days, and Noah visits every 4 days. If they both visited the library today, how together again?

• • Solution: Multiples of 6: 6, 12, 4: 4, 8, 12. Lily and Noah will both visit the library again in 12 days

2. At the 15 apples, 9 bananas, and 18 oranges. The manager wants to arrange the fruits into equal baskets. What is the greatest number of baskets that can be made?

• • Solution: Factors of 15: 1, 3, 5, 15; 9:13,9 18: 1, 2, 3, 6, 9, 18. The greatest number of baskets that can be made is 3.

3. A baker has 45 chocolate cookies and 81 vanilla cookies. She wants to decide on the two boxes so that each box has the same number of cookies without changing flavors. What is the greatest number of boxes she can use?

• • Solution: Factors of 45: 1, 3, 5, 9, 15, 45;81: 1, 3, 9, 27, 81. The greatest number of baskets that can be made is 9.

  This exercise is a mix of GCF and LCF. Above, we have a total of three queries in the form of sentences. To solve this exercise, kids need to follow some rules. So the first one is to read the question carefully and, after that, find the multiples of the given number. After finding the multiples, we need to find the number that is common to both multiples. So we hope our concept is helpful for kids, as they have learned new concepts. We want kids to solve this without any help.

Q1. My child is struggling with factoring larger numbers. What should we do?

Answer: Encourage them to use the “Divisibility Rules” sheet first. Knowing if a number is divisible by 2, 3, or 5 helps narrow down the possible factors quickly.

Q2. Why are factor trees useful?

Answer: Factor trees turn abstract mental math into a visual map, making it much easier to keep track of prime factors for large numbers.

Q3. Are these worksheets aligned with the standard curriculum?

Answer: Yes, our worksheets are developed by experienced educators to align with standard Grade 5 mathematics learning outcomes, focusing on both conceptual understanding and procedural fluency.

Developed by our Content Team, this worksheet strengthens student learning.
