Prime factorization of $$$1233$$$
Your Input
Find the prime factorization of $$$1233$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$1233$$$ is divisible by $$$2$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$3$$$.
Determine whether $$$1233$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$1233$$$ by $$${\color{green}3}$$$: $$$\frac{1233}{3} = {\color{red}411}$$$.
Determine whether $$$411$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$411$$$ by $$${\color{green}3}$$$: $$$\frac{411}{3} = {\color{red}137}$$$.
The prime number $$${\color{green}137}$$$ has no other factors then $$$1$$$ and $$${\color{green}137}$$$: $$$\frac{137}{137} = {\color{red}1}$$$.
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: $$$1233 = 3^{2} \cdot 137$$$.
Answer
The prime factorization is $$$1233 = 3^{2} \cdot 137$$$A.
