Revealed: Is it a Prime or Composite Number? - postfix
Prime numbers are whole numbers greater than 1 that have only two distinct positive divisors: 1 and themselves. For example, 5 and 7 are prime numbers, as they cannot be divided evenly by any other number except for 1 and themselves. On the other hand, composite numbers are whole numbers greater than 1 that have more than two distinct positive divisors. For example, 4 and 6 are composite numbers, as they can be divided evenly by multiple numbers, such as 2.
