Prime factorization of $$$3843$$$
Your Input
Find the prime factorization of $$$3843$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$3843$$$ is divisible by $$$2$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$3$$$.
Determine whether $$$3843$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$3843$$$ by $$${\color{green}3}$$$: $$$\frac{3843}{3} = {\color{red}1281}$$$.
Determine whether $$$1281$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$1281$$$ by $$${\color{green}3}$$$: $$$\frac{1281}{3} = {\color{red}427}$$$.
Determine whether $$$427$$$ is divisible by $$$3$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$5$$$.
Determine whether $$$427$$$ is divisible by $$$5$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$7$$$.
Determine whether $$$427$$$ is divisible by $$$7$$$.
It is divisible, thus, divide $$$427$$$ by $$${\color{green}7}$$$: $$$\frac{427}{7} = {\color{red}61}$$$.
The prime number $$${\color{green}61}$$$ has no other factors then $$$1$$$ and $$${\color{green}61}$$$: $$$\frac{61}{61} = {\color{red}1}$$$.
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: $$$3843 = 3^{2} \cdot 7 \cdot 61$$$.
Answer
The prime factorization is $$$3843 = 3^{2} \cdot 7 \cdot 61$$$A.
