Prime factorization of $$$478$$$
Your Input
Find the prime factorization of $$$478$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$478$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$478$$$ by $$${\color{green}2}$$$: $$$\frac{478}{2} = {\color{red}239}$$$.
The prime number $$${\color{green}239}$$$ has no other factors then $$$1$$$ and $$${\color{green}239}$$$: $$$\frac{239}{239} = {\color{red}1}$$$.
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: $$$478 = 2 \cdot 239$$$.
Answer
The prime factorization is $$$478 = 2 \cdot 239$$$A.
