If completed correctly, the bottom branch of a factor tree will be the prime factorization of the number at the top.

17, being a prime number, has one prime factor, itself. Whether you call that one branch or no branches, it won't be a tree.

A factor tree is a way to notate the process of finding the prime factorization. If completed successfully, the bottom row (branch) will display the prime factorization of the number you started with.

A Factor tree is when you put your number there and then find what makes that answer, you know it is done when you have all prime numbers. ~6th grader @ Celia Hays Elementary

A factor tree is when you get a number, say, 180 and pick any numbers ( which are factors of the number), here is an example.180/ \30 6/ \ / \6 5 2 3/ \2 3When you look at the tree you see the numbers below it are factors of that number. However, you do not keep adding numbers below it if it is prime. Prime means that the number's factors are just one and the number itself (ex. 17: 1,17

The factor tree is awsome!
