Find the prime factorization of $1185$.

### Solution

Start with the number $2$.

Determine whether $1185$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $1185$ is divisible by $3$.

It is divisible, thus, divide $1185$ by ${\color{green}3}$: $\frac{1185}{3} = {\color{red}395}$.

Determine whether $395$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $395$ is divisible by $5$.

It is divisible, thus, divide $395$ by ${\color{green}5}$: $\frac{395}{5} = {\color{red}79}$.

The prime number ${\color{green}79}$ has no other factors then $1$ and ${\color{green}79}$: $\frac{79}{79} = {\color{red}1}$.

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: $1185 = 3 \cdot 5 \cdot 79$.

The prime factorization is $1185 = 3 \cdot 5 \cdot 79$A.
