Answer 1

Step 1. Determine the prime factorization of $396.$

A prime number is one that only has two factors: one and the number itself.
Finding which prime numbers multiply to produce the original number is known as "prime factorization."

$\begin{array}{rcl}396& =& 2\times 198\\ & =& 2\times 2\times 99\\ & =& 2\times 2\times 3\times 33\\ & =& 2\times 2\times 3\times 3\times 11\end{array}$

Hence, the prime factorization of $396$ is $2,3$ and $11$.
