Find the prime factorization of $3091$.

### Solution

Start with the number $2$.

Determine whether $3091$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $3091$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $3091$ is divisible by $5$.

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

The next prime number is $7$.

Determine whether $3091$ is divisible by $7$.

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

The next prime number is $11$.

Determine whether $3091$ is divisible by $11$.

It is divisible, thus, divide $3091$ by ${\color{green}11}$: $\frac{3091}{11} = {\color{red}281}$.

The prime number ${\color{green}281}$ has no other factors then $1$ and ${\color{green}281}$: $\frac{281}{281} = {\color{red}1}$.

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: $3091 = 11 \cdot 281$.

The prime factorization is $3091 = 11 \cdot 281$A.
