Find the prime factorization of $4459$.

### Solution

Start with the number $2$.

Determine whether $4459$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $4459$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $4459$ is divisible by $5$.

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

The next prime number is $7$.

Determine whether $4459$ is divisible by $7$.

It is divisible, thus, divide $4459$ by ${\color{green}7}$: $\frac{4459}{7} = {\color{red}637}$.

Determine whether $637$ is divisible by $7$.

It is divisible, thus, divide $637$ by ${\color{green}7}$: $\frac{637}{7} = {\color{red}91}$.

Determine whether $91$ is divisible by $7$.

It is divisible, thus, divide $91$ by ${\color{green}7}$: $\frac{91}{7} = {\color{red}13}$.

The prime number ${\color{green}13}$ has no other factors then $1$ and ${\color{green}13}$: $\frac{13}{13} = {\color{red}1}$.

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: $4459 = 7^{3} \cdot 13$.

The prime factorization is $4459 = 7^{3} \cdot 13$A.
