Find the prime factorization of $2123$.

### Solution

Start with the number $2$.

Determine whether $2123$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $2123$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $2123$ is divisible by $5$.

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

The next prime number is $7$.

Determine whether $2123$ is divisible by $7$.

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

The next prime number is $11$.

Determine whether $2123$ is divisible by $11$.

It is divisible, thus, divide $2123$ by ${\color{green}11}$: $\frac{2123}{11} = {\color{red}193}$.

The prime number ${\color{green}193}$ has no other factors then $1$ and ${\color{green}193}$: $\frac{193}{193} = {\color{red}1}$.

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: $2123 = 11 \cdot 193$.

The prime factorization is $2123 = 11 \cdot 193$A.
