To factor an expression using GCF we need to first factorate the numbers. We have:

We now need to take the factors that repeat. We have "2" repeating twice and "3" repeating once. So we have:

GCF= 2*2*3=12
We now divide both numbers by the GCF, we have:


We can represent the expression as the product of the GCF with the divisions above.
