Find the prime factorization of $3344$.

### Solution

Start with the number $2$.

Determine whether $3344$ is divisible by $2$.

It is divisible, thus, divide $3344$ by ${\color{green}2}$: $\frac{3344}{2} = {\color{red}1672}$.

Determine whether $1672$ is divisible by $2$.

It is divisible, thus, divide $1672$ by ${\color{green}2}$: $\frac{1672}{2} = {\color{red}836}$.

Determine whether $836$ is divisible by $2$.

It is divisible, thus, divide $836$ by ${\color{green}2}$: $\frac{836}{2} = {\color{red}418}$.

Determine whether $418$ is divisible by $2$.

It is divisible, thus, divide $418$ by ${\color{green}2}$: $\frac{418}{2} = {\color{red}209}$.

Determine whether $209$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $209$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $209$ is divisible by $5$.

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

The next prime number is $7$.

Determine whether $209$ is divisible by $7$.

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

The next prime number is $11$.

Determine whether $209$ is divisible by $11$.

It is divisible, thus, divide $209$ by ${\color{green}11}$: $\frac{209}{11} = {\color{red}19}$.

The prime number ${\color{green}19}$ has no other factors then $1$ and ${\color{green}19}$: $\frac{19}{19} = {\color{red}1}$.

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: $3344 = 2^{4} \cdot 11 \cdot 19$.

The prime factorization is $3344 = 2^{4} \cdot 11 \cdot 19$A.
