Answer
We will use the didvision method as shown below:
$\begin{array}{c|c}3&1323\\\hline3&441\\\hline3&147\\\hline7&49\\\hline7&7\\\hline&1\end{array}$
$\therefore1323=3\times3\times3\times7\times7\times1$
$=3^3\times7^2$
$\begin{array}{c|c}3&1323\\\hline3&441\\\hline3&147\\\hline7&49\\\hline7&7\\\hline&1\end{array}$
$\therefore1323=3\times3\times3\times7\times7\times1$
$=3^3\times7^2$
