Find the prime factorization of $2118$.

### Solution

Start with the number $2$.

Determine whether $2118$ is divisible by $2$.

It is divisible, thus, divide $2118$ by ${\color{green}2}$: $\frac{2118}{2} = {\color{red}1059}$.

Determine whether $1059$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $1059$ is divisible by $3$.

It is divisible, thus, divide $1059$ by ${\color{green}3}$: $\frac{1059}{3} = {\color{red}353}$.

The prime number ${\color{green}353}$ has no other factors then $1$ and ${\color{green}353}$: $\frac{353}{353} = {\color{red}1}$.

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: $2118 = 2 \cdot 3 \cdot 353$.

The prime factorization is $2118 = 2 \cdot 3 \cdot 353$A.
