Find the prime factorization of $2985$.

### Solution

Start with the number $2$.

Determine whether $2985$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $2985$ is divisible by $3$.

It is divisible, thus, divide $2985$ by ${\color{green}3}$: $\frac{2985}{3} = {\color{red}995}$.

Determine whether $995$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $995$ is divisible by $5$.

It is divisible, thus, divide $995$ by ${\color{green}5}$: $\frac{995}{5} = {\color{red}199}$.

The prime number ${\color{green}199}$ has no other factors then $1$ and ${\color{green}199}$: $\frac{199}{199} = {\color{red}1}$.

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: $2985 = 3 \cdot 5 \cdot 199$.

The prime factorization is $2985 = 3 \cdot 5 \cdot 199$A.
