How do you find the smallest prime factor of a number?
Start dividing the number by the smallest prime number i.e., 2, followed by 3, 5, and so on to find the smallest prime factor of the number. Again, divide the quotient by the smallest prime number. Repeat the process, until the quotient becomes 1 after repeated division.
Why is 2 the lowest prime number?
For any number to be a prime number it should have exactly two factors that are the number itself and ‘one’.

Which is the smallest prime factor of a number?
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. How to efficiently find prime factors of all numbers till n? Check out this Author’s contributed articles.
