Find the GCF of 30m + 12n .

To find the Greatest Common Factor (GCF) of 30m and 12n, we need to find the largest expression that can be divided evenly into both terms.

First, let's break down each expression into its prime factors:

30m = 2 * 3 * 5 * m
12n = 2 * 2 * 3 * n

Now, we can identify the common prime factors for both expressions, which are 2 and 3:

2 * 3 = 6

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

positive?

Apologies for the oversight. You are correct. The GCF is positive. So, the GCF of 30m and 12n is +6.
