Properties of Factors
- Each number is a factor of itself. Eg. 18 is a factor of itself.
- 2 is the only even prime factor any number can have.
- Every factor of a number is an exact divisor of that number, example 1, 2, 3, 6, 9, 18 are exact divisors of 18.
- 1 is the common and smallest natural factor every number can have.
- Every number is a factor of zero (0), since 18 x 0 = 0.
