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
