Find the prime factorization of $3934$.

### Solution

Start with the number $2$.

Determine whether $3934$ is divisible by $2$.

It is divisible, thus, divide $3934$ by ${\color{green}2}$: $\frac{3934}{2} = {\color{red}1967}$.

Determine whether $1967$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $1967$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $1967$ is divisible by $5$.

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

The next prime number is $7$.

Determine whether $1967$ is divisible by $7$.

It is divisible, thus, divide $1967$ by ${\color{green}7}$: $\frac{1967}{7} = {\color{red}281}$.

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: $3934 = 2 \cdot 7 \cdot 281$.

The prime factorization is $3934 = 2 \cdot 7 \cdot 281$A.
