Find the prime factorization of $2938$.

### Solution

Start with the number $2$.

Determine whether $2938$ is divisible by $2$.

It is divisible, thus, divide $2938$ by ${\color{green}2}$: $\frac{2938}{2} = {\color{red}1469}$.

Determine whether $1469$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $1469$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $1469$ is divisible by $5$.

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

The next prime number is $7$.

Determine whether $1469$ is divisible by $7$.

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

The next prime number is $11$.

Determine whether $1469$ is divisible by $11$.

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

The next prime number is $13$.

Determine whether $1469$ is divisible by $13$.

It is divisible, thus, divide $1469$ by ${\color{green}13}$: $\frac{1469}{13} = {\color{red}113}$.

The prime number ${\color{green}113}$ has no other factors then $1$ and ${\color{green}113}$: $\frac{113}{113} = {\color{red}1}$.

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: $2938 = 2 \cdot 13 \cdot 113$.

The prime factorization is $2938 = 2 \cdot 13 \cdot 113$A.
