Find the prime factorization of $1930$.

### Solution

Start with the number $2$.

Determine whether $1930$ is divisible by $2$.

It is divisible, thus, divide $1930$ by ${\color{green}2}$: $\frac{1930}{2} = {\color{red}965}$.

Determine whether $965$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $965$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $965$ is divisible by $5$.

It is divisible, thus, divide $965$ by ${\color{green}5}$: $\frac{965}{5} = {\color{red}193}$.

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: $1930 = 2 \cdot 5 \cdot 193$.

The prime factorization is $1930 = 2 \cdot 5 \cdot 193$A.
