$30b^2 = 10b^2(3)$

$80b^2 = 10b^2(8)$

$20b^3 = 10b^2(2b)$

$\text {GCF = } 10b^2$

Hello there!

The right prime factorization is

2*2*2*3*11 because 2 and 3 and 11 are prime.

Take a look at the words "prime" and "factorization"

Can you see something that looks like "prime factors?" Exactly!

2 is prime. 3 is prime. 11 is also prime.

A prime number is only divisible by 1 and itself.

A=Addition

S=Subtraction
