Find the prime factorization of $755$.

### Solution

Start with the number $2$.

Determine whether $755$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $755$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $755$ is divisible by $5$.

It is divisible, thus, divide $755$ by ${\color{green}5}$: $\frac{755}{5} = {\color{red}151}$.

The prime number ${\color{green}151}$ has no other factors then $1$ and ${\color{green}151}$: $\frac{151}{151} = {\color{red}1}$.

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: $755 = 5 \cdot 151$.

The prime factorization is $755 = 5 \cdot 151$A.
