Prime factorization of $$$2630$$$
Your Input
Find the prime factorization of $$$2630$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$2630$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$2630$$$ by $$${\color{green}2}$$$: $$$\frac{2630}{2} = {\color{red}1315}$$$.
Determine whether $$$1315$$$ is divisible by $$$2$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$3$$$.
Determine whether $$$1315$$$ is divisible by $$$3$$$.
Since it is not divisible, move to the next prime number.
The next prime number is $$$5$$$.
Determine whether $$$1315$$$ is divisible by $$$5$$$.
It is divisible, thus, divide $$$1315$$$ by $$${\color{green}5}$$$: $$$\frac{1315}{5} = {\color{red}263}$$$.
The prime number $$${\color{green}263}$$$ has no other factors then $$$1$$$ and $$${\color{green}263}$$$: $$$\frac{263}{263} = {\color{red}1}$$$.
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: $$$2630 = 2 \cdot 5 \cdot 263$$$.
Answer
The prime factorization is $$$2630 = 2 \cdot 5 \cdot 263$$$A.
