Question

What is the greatest common factor of 30b^2, 80b^2, and 20b^2

Answer 1

10b²

Explanation:

First, let's look at the coefficients. The greatest common factor of all three numbers 30, 80, and 20, is 10. Now, let's look at the variables. All three terms are divisible by b² (with no remainder). We can combine 10 and b² so they become one term, and that is the GCF. 10b².
