1. Prime Factorization
Prime factorization or integer factorization of a number is the determination of the set of prime numbers which multiply together to give the original integer. It is also known as prime decomposition.

2. Prime Numbers
A prime number can only be divided by 1 or itself, so it cannot be factored any further! 

3. Not Prime Numbers
(Composite)
Prime Numbers

4. Know Your Divisibility Rules!!

5. Factor Trees

6. Hmmm… Writing Prime Factors in EXPONENTIAL NOTATION!!
List all of your prime factors (2 x 2 x 3 x 3 x 3)
Write the exponential notation (2 x 3 )
Evaluate to check (4 x 27 = 108) 2 3

7. Use a Factor Tree to help find the prime factors of each composite number. Then “write the number as a product of its prime factors in exponential notation.”
