Find the prime factorization of $3357$.

### Solution

Start with the number $2$.

Determine whether $3357$ is divisible by $2$.

Since it is not divisible, move to the next prime number.

The next prime number is $3$.

Determine whether $3357$ is divisible by $3$.

It is divisible, thus, divide $3357$ by ${\color{green}3}$: $\frac{3357}{3} = {\color{red}1119}$.

Determine whether $1119$ is divisible by $3$.

It is divisible, thus, divide $1119$ by ${\color{green}3}$: $\frac{1119}{3} = {\color{red}373}$.

The prime number ${\color{green}373}$ has no other factors then $1$ and ${\color{green}373}$: $\frac{373}{373} = {\color{red}1}$.

Since we have obtained $1$, we are done.

Now, just count the number of occurences of the divisors (green numbers), and write down the prime factorization: $3357 = 3^{2} \cdot 373$.

The prime factorization is $3357 = 3^{2} \cdot 373$A.
