Find the prime factorization of $1599$.

### Solution

Start with the number $2$.

Determine whether $1599$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $1599$ is divisible by $3$.

It is divisible, thus, divide $1599$ by ${\color{green}3}$: $\frac{1599}{3} = {\color{red}533}$.

Determine whether $533$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $533$ is divisible by $5$.

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

The next prime number is $7$.

Determine whether $533$ is divisible by $7$.

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

The next prime number is $11$.

Determine whether $533$ is divisible by $11$.

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

The next prime number is $13$.

Determine whether $533$ is divisible by $13$.

It is divisible, thus, divide $533$ by ${\color{green}13}$: $\frac{533}{13} = {\color{red}41}$.

The prime number ${\color{green}41}$ has no other factors then $1$ and ${\color{green}41}$: $\frac{41}{41} = {\color{red}1}$.

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: $1599 = 3 \cdot 13 \cdot 41$.

The prime factorization is $1599 = 3 \cdot 13 \cdot 41$A.
