Deducing Composites and Factors at eTutorWorld

Factors are numbers that you multiply to get another number

  • A prime number has exactly two factors: 1 and itself.
  • A composite number has more than two factors.
  • Co prime numbers have only 1 as a common factor.

The number 1 is special.  It only has one factor — just itself!  So, 1 is neither prime nor composite.

To determine if a number is prime or composite, follow these steps:

  1. Find all factors of the number.
  2. If the number has only two factors, 1 and itself, then it is prime.
  3. If the number has more than two factors, then it is composite.
