Question

What is the GCF of 32ab 3 and 40a 2?

Answer 1

In this question , we have to find the GCF of

$32ab^3 \ and \ 40a^2$

First we write each of them in the faactored form, that is

$32ab^3 = 2*2*2*2*2*a*b*b*b 40a^2 = 2*2*2*5*a*a$

Now we check for all the common factors, which are

$= 2*2*2 *a = 8a$

So the required GCF is 8a .
