To find the factor tree for 193, you start by determining the prime factors of 193. Since 193 is a prime number itself, the factor tree for 193 would simply consist of the number 193 at the top, as it cannot be broken down further into smaller prime factors. Therefore, the factor tree for 193 would just be a single branch with 193 as the prime factor.
87 3,29
87 = 3*29
87 3,29 Not much of a tree. More like a factor shrub.
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.

29x3 both prime so your done
29 is already prime. No tree. 87 3,29 Since there are no common prime factors, the GCF is 1.
There are 2 factor pairs of 87:87 = 1 x 8787 = 3 x 29
87 is the only composite factor of 87.
1, 3, 29, 87
87 is the only composite factor of 87.
The greatest common factor of 87 , 120 = 3
