Prime factorization of $$$4065$$$
Your Input
Find the prime factorization of $$$4065$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$4065$$$ is divisible by $$$2$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$3$$$.
Determine whether $$$4065$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$4065$$$ by $$${\color{green}3}$$$: $$$\frac{4065}{3} = {\color{red}1355}$$$.
Determine whether $$$1355$$$ is divisible by $$$3$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$5$$$.
Determine whether $$$1355$$$ is divisible by $$$5$$$.
It is divisible, thus, divide $$$1355$$$ by $$${\color{green}5}$$$: $$$\frac{1355}{5} = {\color{red}271}$$$.
The prime number $$${\color{green}271}$$$ has no other factors then $$$1$$$ and $$${\color{green}271}$$$: $$$\frac{271}{271} = {\color{red}1}$$$.
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: $$$4065 = 3 \cdot 5 \cdot 271$$$.
Answer
The prime factorization is $$$4065 = 3 \cdot 5 \cdot 271$$$A.
