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

The next prime number is $3$.

Determine whether $1819$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $1819$ is divisible by $5$.

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

The next prime number is $7$.

Determine whether $1819$ is divisible by $7$.

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

The next prime number is $11$.

Determine whether $1819$ is divisible by $11$.

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

The next prime number is $13$.

Determine whether $1819$ is divisible by $13$.

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

The next prime number is $17$.

Determine whether $1819$ is divisible by $17$.

It is divisible, thus, divide $1819$ by ${\color{green}17}$: $\frac{1819}{17} = {\color{red}107}$.

The prime number ${\color{green}107}$ has no other factors then $1$ and ${\color{green}107}$: $\frac{107}{107} = {\color{red}1}$.

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: $1819 = 17 \cdot 107$.

The prime factorization is $1819 = 17 \cdot 107$A.
