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.
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 use factor rainbows, fireworks, ladders, etc. They're all the same thing.
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.
