For this case, we must find the GCF of the following expression:
[tex]4xy + 12w + 12z[/tex]
By definition, the Greatest Common Factor is given by the greatest factor that divides all the terms of the expression without leaving remainder.
We find the factors of 4 and 12:
[tex]4: 1,2,4\\12: 1,2,3,4,6,12[/tex]
On the other hand, the variables are not repeated in the terms of the expression.
Thus, we can rewrite the expression as:
[tex]4 (xy + 3w + 3z)[/tex]
Answer:
[tex]4 (xy + 3w + 3z)[/tex]
