Find the prime factorization of $4318$.

### Solution

Start with the number $2$.

Determine whether $4318$ is divisible by $2$.

It is divisible, thus, divide $4318$ by ${\color{green}2}$: $\frac{4318}{2} = {\color{red}2159}$.

Determine whether $2159$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $2159$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $2159$ is divisible by $5$.

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

The next prime number is $7$.

Determine whether $2159$ is divisible by $7$.

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

The next prime number is $11$.

Determine whether $2159$ is divisible by $11$.

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

The next prime number is $13$.

Determine whether $2159$ is divisible by $13$.

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

The next prime number is $17$.

Determine whether $2159$ is divisible by $17$.

It is divisible, thus, divide $2159$ by ${\color{green}17}$: $\frac{2159}{17} = {\color{red}127}$.

The prime number ${\color{green}127}$ has no other factors then $1$ and ${\color{green}127}$: $\frac{127}{127} = {\color{red}1}$.

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: $4318 = 2 \cdot 17 \cdot 127$.

The prime factorization is $4318 = 2 \cdot 17 \cdot 127$A.
