Prime factorization of $$$2126$$$
Your Input
Find the prime factorization of $$$2126$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$2126$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$2126$$$ by $$${\color{green}2}$$$: $$$\frac{2126}{2} = {\color{red}1063}$$$.
The prime number $$${\color{green}1063}$$$ has no other factors then $$$1$$$ and $$${\color{green}1063}$$$: $$$\frac{1063}{1063} = {\color{red}1}$$$.
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: $$$2126 = 2 \cdot 1063$$$.
Answer
The prime factorization is $$$2126 = 2 \cdot 1063$$$A.
