How to find Greatest common factor?
The greatest common factor, as the name implies, is the greatest among all common factors among the quantities given.
We can factorize the quantities in the smallest relative factors possible (one level of factors over which all quantities can form themselves), and collect as many common factors as we could. Those will together compose GCF(The greatest common factor).
Given expression;
[tex]12a^4b^3 + 8a^3b^2[/tex]
Taking common factor
[tex]4a^3b^2(3ab + 2)[/tex]
Thus, the common factor is [tex]4a^3b^2[/tex]. so option A is correct.
