Prime factorization of $$$522$$$
Your Input
Find the prime factorization of $$$522$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$522$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$522$$$ by $$${\color{green}2}$$$: $$$\frac{522}{2} = {\color{red}261}$$$.
Determine whether $$$261$$$ is divisible by $$$2$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$3$$$.
Determine whether $$$261$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$261$$$ by $$${\color{green}3}$$$: $$$\frac{261}{3} = {\color{red}87}$$$.
Determine whether $$$87$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$87$$$ by $$${\color{green}3}$$$: $$$\frac{87}{3} = {\color{red}29}$$$.
The prime number $$${\color{green}29}$$$ has no other factors then $$$1$$$ and $$${\color{green}29}$$$: $$$\frac{29}{29} = {\color{red}1}$$$.
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: $$$522 = 2 \cdot 3^{2} \cdot 29$$$.
Answer
The prime factorization is $$$522 = 2 \cdot 3^{2} \cdot 29$$$A.
