Find the prime factorization of $4069$.

### Solution

Start with the number $2$.

Determine whether $4069$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $4069$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $4069$ is divisible by $5$.

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

The next prime number is $7$.

Determine whether $4069$ is divisible by $7$.

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

The next prime number is $11$.

Determine whether $4069$ is divisible by $11$.

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

The next prime number is $13$.

Determine whether $4069$ is divisible by $13$.

It is divisible, thus, divide $4069$ by ${\color{green}13}$: $\frac{4069}{13} = {\color{red}313}$.

The prime number ${\color{green}313}$ has no other factors then $1$ and ${\color{green}313}$: $\frac{313}{313} = {\color{red}1}$.

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: $4069 = 13 \cdot 313$.

The prime factorization is $4069 = 13 \cdot 313$A.
