How do you find the GCF of 12 and 18?

Answer 1

Nova Allen

LIst all of the factors of 12 and 18. Then find the unique factors and multiple them.

the factors of 12 are # 2 xx 2 xx 3 # or # 2^2 xx 3#

the factors of 18 are # 2 xx 3 xx 3 # or # 2 xx 3^2#

The GCF must contain one 2 because there are two 2s in 12 and one 2 in 18.

The GCF must contain one 3 because there are two 3s in 18 and one 3 in 12.

So the GCG is # 2 xx 3# =6
