A factor tree is a representation of the process of finding the prime factorization of a given number.
a factor tree
A factor tree.
When you want to find the prime factorization of a composite number.
You can use factor rainbows, fireworks, ladders, etc. They're all the same thing.
No because you have to have a prime number besides 1 like 2,5,7 because every time you use a factor tree and you put a 1 as prime you keep getting one every time.So one can not be use as a factor when doing a factor tree.
Factor tree are used to find factors of a number. It is one of the most preferred methods for finding factor of a number by many people. However, not everyone in every country knows about this method.
you can find the factors of a number my using a factor tree
You cannot "solve" a single number!

109 109 x 1 This is all there is to the factor tree, because 109 is a prime number. Normally, I wouldn't use 1 in a factor tree, but I do in this case to make it clear that I have done a factor tree, since 109 is only divisible by itself and 1.
