Math 6 - Prime Factorization & GCF Practice

Front

What is prime factorization?

Back

Prime factorization is the process of breaking down a number into its prime factors, which are the prime numbers that multiply together to give the original number.

Front

What is a factor tree?

Back

A factor tree is a visual representation used to find the prime factorization of a number by breaking it down into its factors until all factors are prime.
