Question

find the gcf of the following 46a 50a^2

Answer 1

hint:
we have the subsequent factorizations:
\[\Large \begin{gathered}
46a = 2 \times 23 \times a \hfill \\
50{a^2} = 2 \times {5^2} \times {a^2} \hfill \\
\end{gathered} \]

Answer 2

now, the great common factor is given by the product of common factors to those factorization, each with the littlest exponent
