What is prime factorization method?

Both methods start out with a factor tree. A factor tree is a diagram that is used to break down a number into its factors until all the numbers left are prime. The first way you can use a factor tree to find the factorization of a number is to divide out prime numbers only. Let's factor 24 using this method.
