"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**
