How to Find the Composite Number?

The procedures to find whether a given number is prime or composite:

  • Find all the factors of the positive integer
  • A number is said to be prime if it has only two factors, 1 and itself
  • If the number has more than two factors, then it is a composite
Example: Find if 14 is a composite number. Let us find the factors of 14.

  • 14÷1 = 14
  • 14÷2 = 7
  • 14÷7 = 2
  • 14÷14 = 1

As we can see, the factors of 14 are 1,2,7 and 14, so it is a composite number.
