Prime factorization of $$$2274$$$
Your Input
Find the prime factorization of $$$2274$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$2274$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$2274$$$ by $$${\color{green}2}$$$: $$$\frac{2274}{2} = {\color{red}1137}$$$.
Determine whether $$$1137$$$ is divisible by $$$2$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$3$$$.
Determine whether $$$1137$$$ is divisible by $$$3$$$.
It is divisible, thus, divide $$$1137$$$ by $$${\color{green}3}$$$: $$$\frac{1137}{3} = {\color{red}379}$$$.
The prime number $$${\color{green}379}$$$ has no other factors then $$$1$$$ and $$${\color{green}379}$$$: $$$\frac{379}{379} = {\color{red}1}$$$.
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: $$$2274 = 2 \cdot 3 \cdot 379$$$.
Answer
The prime factorization is $$$2274 = 2 \cdot 3 \cdot 379$$$A.
