Verified Answer :

The greatest common factor of sets of mathematical expression is that which can divide both and give the least answer. 
For the first set, the GCF is equal to 4ab^2. 
For the second set of mathematical expressions, the GCF is 4ab^2.

Answer: The greatest common factor of \(8a^3b^2\ and\ 12ab^4\) is \(4ab^2\).

Step-by-step explanation:

Given expressions: \(8a^3b^2\ and\ 12ab^4\)

We can write the first expression as

\(8a^3b^2=2\times2\times2\times a\times a\times a\times b\times b\\12ab^4=2\times2\times3\times a\times\ b\times b\times b\times b\)

We can see the greatest common factors in both the expressions as

GCF=\(2\times2\times a\times b\times b=4ab^2\)

Hence, the greatest common factor of \(8a^3b^2\ and\ 12ab^4\) is \(4ab^2\).
