Prime factorization of $$$2057$$$
Your Input
Find the prime factorization of $$$2057$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$2057$$$ is divisible by $$$2$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$3$$$.
Determine whether $$$2057$$$ is divisible by $$$3$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$5$$$.
Determine whether $$$2057$$$ is divisible by $$$5$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$7$$$.
Determine whether $$$2057$$$ is divisible by $$$7$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$11$$$.
Determine whether $$$2057$$$ is divisible by $$$11$$$.
It is divisible, thus, divide $$$2057$$$ by $$${\color{green}11}$$$: $$$\frac{2057}{11} = {\color{red}187}$$$.
Determine whether $$$187$$$ is divisible by $$$11$$$.
It is divisible, thus, divide $$$187$$$ by $$${\color{green}11}$$$: $$$\frac{187}{11} = {\color{red}17}$$$.
The prime number $$${\color{green}17}$$$ has no other factors then $$$1$$$ and $$${\color{green}17}$$$: $$$\frac{17}{17} = {\color{red}1}$$$.
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: $$$2057 = 11^{2} \cdot 17$$$.
Answer
The prime factorization is $$$2057 = 11^{2} \cdot 17$$$A.
