In this question , we have to find the GCF of
[tex] 32ab^3 \ and \ 40a^2 [/tex]
First we write each of them in the faactored form, that is
[tex] 32ab^3 = 2*2*2*2*2*a*b*b*b
40a^2 = 2*2*2*5*a*a [/tex]
Now we check for all the common factors, which are
[tex] = 2*2*2 *a = 8a [/tex]
So the required GCF is 8a .
