We want to find the greatest common factor of two given expressions.

The GCF is 15*a*b.

The two expressions are:

45*a^3*b^2 and 15*a*b

To find the greatest common factor, we can rewrite the first expression to get:

45*a^3*b^2 = (3*15)*(a^2*a)*(b*b)

Now remember that we can perform a multiplication in any order we want, so we can rearrange the factors to write this as:

(3*15)*(a^2*a)*(b*b) = (15*a*b)*(3*a^2*b)

Then we have:

45*a^3*b^2 =  (15*a*b)*(3*a^2*b)

So we can see that 15*a*b is a factor of 45*a^3*b^2, then the GCF between 15*a*b and 45*a^3*b^2 is just 15*a*b.
