Prime factorization of $$$86$$$
Your Input
Find the prime factorization of $$$86$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$86$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$86$$$ by $$${\color{green}2}$$$: $$$\frac{86}{2} = {\color{red}43}$$$.
The prime number $$${\color{green}43}$$$ has no other factors then $$$1$$$ and $$${\color{green}43}$$$: $$$\frac{43}{43} = {\color{red}1}$$$.
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: $$$86 = 2 \cdot 43$$$.
Answer
The prime factorization is $$$86 = 2 \cdot 43$$$A.
