# Prime Factorization Calculator

## Find prime factorization step by step

This calculator will find the prime factorization of the given number, with steps shown.

### Your Input

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

### Answer

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