Question

MATH HELP!!!!!!!!!!!!!!!!

Answer 1

Answer:

2a

Step-by-step explanation:

Look at the numbers first: 12, 28, 42

12 = 2 * 2 * 3

28 = 2 * 2 * 7

42 = 2 * 3 * 7

The only factor all numbers have in common is 2.

GCF of numbers = 2

Now look at the variables: a^2b^6, a^4, ab^3

a^2b^6 = aabbbbbb

a^4 = aaaa

ab^3 = abbb

The only variable all expressions have in common is a.

GCF of variables = a

GCF of the three monomials is: 2a
