Find the prime factorization of $75$.

## Solution

Start with the number $2$.

Determine whether $75$ is divisible by $2$.

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

The next prime number is $3$.

Determine whether $75$ is divisible by $3$.

It is divisible, thus, divide $75$ by $\color{green}{3}$: $\frac{75}{3} = \color{red}{25}$.

Determine whether $25$ is divisible by $3$.

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

The next prime number is $5$.

Determine whether $25$ is divisible by $5$.

It is divisible, thus, divide $25$ by $\color{green}{5}$: $\frac{25}{5} = \color{red}{5}$.

The prime number $\color{green}{5}$ has no other factors then $1$ and $\color{green}{5}$: $\frac{5}{5} = \color{red}{1}$.

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: $75 = 3 \cdot 5^{2}$.

The prime factorization is $75 = 3 \cdot 5^{2}$A.
