87 3,29 Not much of a tree. More like a factor shrub.
29 is prime. No tree. 87 3,29
Use a factor tree. 87 3,29
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.
29 is already prime. No tree. 87 3,29 Since there are no common prime factors, the GCF is 1.

29x3 both prime so your done
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.
