finde the gcf of 15q+6

To find the greatest common factor (GCF) of the expression 15q + 6, we need to factor out the smallest possible terms common to both terms.

First, let's factor out a 3 from both terms:
15q + 6 = 3(5q + 2)

The expression 5q + 2 cannot be further factored, so the GCF of 15q + 6 is 3.
