Find the prime factorization of $1017$.

### Solution

Start with the number $2$.

Determine whether $1017$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $1017$ is divisible by $3$.

It is divisible, thus, divide $1017$ by ${\color{green}3}$: $\frac{1017}{3} = {\color{red}339}$.

Determine whether $339$ is divisible by $3$.

It is divisible, thus, divide $339$ by ${\color{green}3}$: $\frac{339}{3} = {\color{red}113}$.

The prime number ${\color{green}113}$ has no other factors then $1$ and ${\color{green}113}$: $\frac{113}{113} = {\color{red}1}$.

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: $1017 = 3^{2} \cdot 113$.

The prime factorization is $1017 = 3^{2} \cdot 113$A.
