## 5 Worksheets on Prime Factorization Activities

Let’s use the worksheets below which are about a few fun activities to practice the prime factorization activities. ## Differences Between Factors & Prime Factors of a Number

A number’s factors are the amount of the numbers multiplied together to get the original number. For instance, the factors of 20 are 4 and 5, since 4 × 5 = 20, whereas the prime factors of a number are the prime integers multiplied to obtain the original number.

As an instance, the prime factors of 20 are 2, 2, and 5, so 2 × 2 × 5 = 20. It should be remembered that not all of a number’s factors are necessarily prime factors. Similar to factoring a number, prime factors of a number only take the prime numbers 2, 3, 5, 7, 11, 13, 17, 19, and so on into account.

Therefore, it can be claimed that the prime factors of a number are those that entirely divide the original number and cannot be divided into more factors. ## 5 Exciting Prime Factorization Activities for Your Youngsters
