Find the prime factorization of $3070$.

### Solution

Start with the number $2$.

Determine whether $3070$ is divisible by $2$.

It is divisible, thus, divide $3070$ by ${\color{green}2}$: $\frac{3070}{2} = {\color{red}1535}$.

Determine whether $1535$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $1535$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $1535$ is divisible by $5$.

It is divisible, thus, divide $1535$ by ${\color{green}5}$: $\frac{1535}{5} = {\color{red}307}$.

The prime number ${\color{green}307}$ has no other factors then $1$ and ${\color{green}307}$: $\frac{307}{307} = {\color{red}1}$.

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: $3070 = 2 \cdot 5 \cdot 307$.

The prime factorization is $3070 = 2 \cdot 5 \cdot 307$A.
