Answer
We will use the didvision method as shown below:
$\begin{array}{c|c}3&945\\\hline3&315\\\hline3&105\\\hline5&35\\\hline7&7\\\hline&1\end{array}$
$\therefore945=3\times3\times3\times5\times7\times1$
$=3^3\times5\times7$
$\begin{array}{c|c}3&945\\\hline3&315\\\hline3&105\\\hline5&35\\\hline7&7\\\hline&1\end{array}$
$\therefore945=3\times3\times3\times5\times7\times1$
