A. 3a b. a^3 c. 4x d. 3pq e. 7^ef f. zxy^1
For this case we have that by definition, the GCF (Greatest Common Factor) is the largest integer that divides the numbers.
We have the following expressions:

We find the factors of 9 and 6:

Thus, the largest number that divides 9 and 6 is 3
It is also observed that "b" is the common variable of both expressions
Therefore, the GCF of the expressions is:
