Prime factorization of $$$1294$$$
Your Input
Find the prime factorization of $$$1294$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$1294$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$1294$$$ by $$${\color{green}2}$$$: $$$\frac{1294}{2} = {\color{red}647}$$$.
The prime number $$${\color{green}647}$$$ has no other factors then $$$1$$$ and $$${\color{green}647}$$$: $$$\frac{647}{647} = {\color{red}1}$$$.
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: $$$1294 = 2 \cdot 647$$$.
Answer
The prime factorization is $$$1294 = 2 \cdot 647$$$A.
