Find the prime factorization of $2715$.

### Solution

Start with the number $2$.

Determine whether $2715$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $2715$ is divisible by $3$.

It is divisible, thus, divide $2715$ by ${\color{green}3}$: $\frac{2715}{3} = {\color{red}905}$.

Determine whether $905$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $905$ is divisible by $5$.

It is divisible, thus, divide $905$ by ${\color{green}5}$: $\frac{905}{5} = {\color{red}181}$.

The prime number ${\color{green}181}$ has no other factors then $1$ and ${\color{green}181}$: $\frac{181}{181} = {\color{red}1}$.

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: $2715 = 3 \cdot 5 \cdot 181$.

The prime factorization is $2715 = 3 \cdot 5 \cdot 181$A.
