About prime factorization

"Prime Factorization" is finding which prime numbers we need to multiply to get the original number.

Example:

Find the prime factorization of 60.

To find prime factorization of 60 start with the smallest prime number that divides 60, in this case 2.

60 ÷ 2 = 30

Now find smallest prime number that divides 30 (again we use 2)

30 ÷ 2 = 15

15 is divisible with 3, so we have:

15 ÷ 3 = 5

5 is divisible with 5, so the prime factorization of 60 is:

2 x 2 x 3 x 5
