Answer:
The GCF or greatest common factor of 12w and 15wz would be 3w
Explanation:
The coefficients 15 and 12 without variables have the factor 3 in common and no others than themselves and 1. After finding 3 is the starting factor, next is to look at the variable after the coefficients which are wz and w. Since both 12w and 15wz only share w, lt will then be 3w as the greatest factor.
Hope this helps!
