Question

Find the greatest common factor of 9m2 and 15c. 8 Х $ ?

Answer 1

We have the following:

`9m^2,15c`

In this case, we first get a common factor between the numbers 9 and 15

`\begin{gathered} 9,15|3 \\ 3,5|3 \\ 1,5|5 \\ 1,1 \\ \text{gcf}=3\cdot3\cdot5=45 \end{gathered}`

Therefore, the answer is:

`45m^2c`
