Each number can be broken down into factors of prime numbers, which is what a prime factorization consists of. Look at the example below:

After looking at the example above and carefully reading the box of instructions on the left, watch this great Math Antics - Prime Factorization video to help you review:

 

After watching the video, what was the definition of prime factorization that he used? Share your answer with your parent or teacher.
