Find the GCF of 30m + 12n please and thank you!.

To find the greatest common factor (GCF) of 30m + 12n, we need to find the largest factor that both terms have in common.

First, let's factor each term:
30m = 2 × 3 × 5 × m
12n = 2 × 2 × 3 × n

Then, we look for the common factors between the two terms, which are 2 and 3. To find the GCF, we take the smallest power of each common factor:
GCF = 2 × 3 = 6

Therefore, the GCF of 30m + 12n is 6.
