Find GCF1st Make Factor Trees for both #’s
2nd List the prime factors in order for each #
3rd Multiply the common pairs
That’s the GCF !

Another Example
GCF(12,18) =
12 = 2 x 2 x 3
18 = 2 x 3 x 3
x2 3 = 6

Another Example
GCF(12,24) =
12 = 2 x 2 x 3
24 = 2 x 2 x 2 x 3
x2 3 = 12x2
Notice the GCF is one of the #’s !
