**Prime Factorization of a Number using a factor tree**

**A Prime Number **is a whole number, greater than 1, that can be evenly

divided only by 1 or itself.

Said another way: a prime is a number whose only factors are itself and 1

For example, 17 is a prime number because its only factors are 1 and 17

**Not: **Factors" are the numbers you multiply together to get another number:

**Prime Factorization:**

A number written as the product of all its prime

factors.

For instance, the prime factorization of 8 is 2×2×2, not just "2". Yes,

2 is the only factor, but you need three copies of it to multiply back

to 8, so the prime factorization includes all three.
