Prime factorization of $$$1317$$$
Your Input
Find the prime factorization of $$$1317$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$1317$$$ is divisible by $$$2$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$3$$$.
Determine whether $$$1317$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$1317$$$ by $$${\color{green}3}$$$: $$$\frac{1317}{3} = {\color{red}439}$$$.
The prime number $$${\color{green}439}$$$ has no other factors then $$$1$$$ and $$${\color{green}439}$$$: $$$\frac{439}{439} = {\color{red}1}$$$.
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: $$$1317 = 3 \cdot 439$$$.
Answer
The prime factorization is $$$1317 = 3 \cdot 439$$$A.
