Use a factor tree to break apart numbers.
ie. 12
...../ \
....2 6
....../ \
.....2 3
The prime factors of 12 are 2, 2, and 3.
A factor tree will show you the prime factorization of 88. Comparing that prime factorization of 88 and another number will you show you the GCF between the two. You need at least two numbers to find a GCF.
Use a factor tree. 400 200,2 100,2,2 50,2,2,2 25,2,2,2,2 5,5,2,2,2,2
A factor tree is a way to notate the process of finding the prime factorization of a given number.
a factor tree
When the bottom branch consists entirely of prime numbers.
The prime factorization.
If completed correctly, the bottom branch of a factor tree will be the prime factorization of the number at the top.
With a factor tree, yes.

13 is already prime, no tree required.
