Question

How do you find the greatest common factor of 12m(r+t)^2 and 3pr(r+t)^4?

Answer 1

`\bf \begin{array}l 12m(r+t)^2&~\hspace{4em}&~3pr(r+t)^4\\&&\\ 4\cdot \underline{3} m\underline{(r+t)^2}&&3pr(r+t)^(2+2)\\&&\\ &&\underline{3} pr(r+t)^2\underline{(r+t)^2} \end{array}~\hfill \stackrel{\textit{\Large GCF}}{3(r+t)^2}`
