Find the prime factorization of $2485$.

### Solution

Start with the number $2$.

Determine whether $2485$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $2485$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $2485$ is divisible by $5$.

It is divisible, thus, divide $2485$ by ${\color{green}5}$: $\frac{2485}{5} = {\color{red}497}$.

Determine whether $497$ is divisible by $5$.

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

The next prime number is $7$.

Determine whether $497$ is divisible by $7$.

It is divisible, thus, divide $497$ by ${\color{green}7}$: $\frac{497}{7} = {\color{red}71}$.

The prime number ${\color{green}71}$ has no other factors then $1$ and ${\color{green}71}$: $\frac{71}{71} = {\color{red}1}$.

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: $2485 = 5 \cdot 7 \cdot 71$.

The prime factorization is $2485 = 5 \cdot 7 \cdot 71$A.
