29x3 both prime so your done

A factor tree of number is (I think) the numbers that multiply together to form a product. They are prime numbers, too.

Prime numbers don't have factor trees. So if you can create a tree, your number's composite.

A factor tree is a representation of the process of finding the prime factorization of a given number.

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

87 3,29 Not much of a tree. More like a factor shrub.

873 x 29Since both 3 and 29 are prime numbers, the factor tree is complete.

It's not necessary for two reasons. First, 29 is a factor of 87 so it will automatically be the GCF of this problem. Second, since factor trees are designed to find prime numbers and 29 is already prime, it doesn't have a tree. But if you insist... 87 3,29 Here we have a factor tree, more like a factor shrub, that shows that the prime factors of 87 are 3 and 29. Since 29 is a factor of 29, the GCF is 29.

The purpose of a factor tree is to notate the process of finding the prime factorization. If a number is already prime, a factor tree is not necessary.

The purpose of a factor tree is to divide a number into prime factors. 1 is not a prime number.

29 is already prime. No tree. 87 3,29 Since there are no common prime factors, the GCF is 1.

There is no factor tree nor factors of 57 as it is a prime number.

13 is a prime number so it doesn't have a factor tree.
