What is a prime number?

Answer   Submitted by Answiki on 06/08/2022 at 06:16:40 PM UTC

A prime number is a natural number that has exactly two distinct positive integer divisors (1 and itself).


For example: 

  • 5 is a prime number, because it is divisible only by 1 and 5 (it is not divisible by 2, 3, or 4).
  • 6 is not a prime number because it is divisible by 1, 2, 3 and 6. It has 4 divisors.
