How do you find the smallest divisor?
How do you find the smallest divisor?
Approach:
- Check if the number is divisible by 2 or not.
- Iterate from i = 3 to sqrt(N) and making a jump of 2.
- If any of the numbers divide N then it is the smallest prime divisor.
- If none of them divide, then N is the answer.
