$\begin{array}{c|c}2&252\\\hline2&126\\\hline3&63\\\hline3&21\\\hline7&7\\\hline&1\end{array}$
$\therefore252=2\times2\times3\times3\times7\times1$
$=2^2\times3^2\times7\times1$
$\begin{array}{c|c}2&252\\\hline2&126\\\hline3&63\\\hline3&21\\\hline7&7\\\hline&1\end{array}$
$\therefore252=2\times2\times3\times3\times7\times1$
$=2^2\times3^2\times7\times1$
