Find the prime factorization of $3155$.

### Solution

Start with the number $2$.

Determine whether $3155$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $3155$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $3155$ is divisible by $5$.

It is divisible, thus, divide $3155$ by ${\color{green}5}$: $\frac{3155}{5} = {\color{red}631}$.

The prime number ${\color{green}631}$ has no other factors then $1$ and ${\color{green}631}$: $\frac{631}{631} = {\color{red}1}$.

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: $3155 = 5 \cdot 631$.

The prime factorization is $3155 = 5 \cdot 631$A.
