Prime factorization of $$$842$$$
Your Input
Find the prime factorization of $$$842$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$842$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$842$$$ by $$${\color{green}2}$$$: $$$\frac{842}{2} = {\color{red}421}$$$.
The prime number $$${\color{green}421}$$$ has no other factors then $$$1$$$ and $$${\color{green}421}$$$: $$$\frac{421}{421} = {\color{red}1}$$$.
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: $$$842 = 2 \cdot 421$$$.
Answer
The prime factorization is $$$842 = 2 \cdot 421$$$A.
