Prime factorization of $$$194$$$

Find the prime factorization of $$$194$$$.

Start with the number $$$2$$$.

Determine whether $$$194$$$ is divisible by $$$2$$$.

It is divisible, thus, divide $$$194$$$ by $$${\color{green}2}$$$: $$$\frac{194}{2} = {\color{red}97}$$$.

The prime number $$${\color{green}97}$$$ has no other factors then $$$1$$$ and $$${\color{green}97}$$$: $$$\frac{97}{97} = {\color{red}1}$$$.

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: $$$194 = 2 \cdot 97$$$.

The prime factorization is $$$194 = 2 \cdot 97$$$A.
