Answer:
The greatest common factor GCF is;
[tex]8ab[/tex]
Explanation:
Given the terms;
[tex]\begin{gathered} 40a^2b \\ \text{and} \\ 48ab^2 \end{gathered}[/tex]
Let us expand each of the terms;
[tex]\begin{gathered} 40a^2b=2\times2\times2\times5\times a\times a\times b \\ 48ab^2=2\times2\times2\times2\times3\times a\times b\times b \\ \end{gathered}[/tex]
then we will write out the greatest common factor;
[tex]\begin{gathered} \text{GCF}=2\times2\times2\times a\times b=8ab \\ \text{GCF}=8ab \end{gathered}[/tex]
Therefore, the greatest common factor GCF is;
[tex]8ab[/tex]
