Factor 9z+18 using the GFC

To factor 9z+18 using the GCF (Greatest Common Factor), we need to find the largest number or expression that divides evenly into both terms.

For 9z and 18, the largest number that divides evenly into both is 9.

We can rewrite 9z+18 as 9(z + 2).

So, the factored form of 9z+18 using the GCF is 9(z + 2).
