About Factors
A factor is a whole number that divides another number exactly without leaving a remainder.
If a × b = n, then a and b are factors of n.
Example: The factors of 24 are:
1, 2, 3, 4, 6, 8, 12, 24
The factor pairs of 24 are:
- 1 × 24 = 24
- 2 × 12 = 24
- 3 × 8 = 24
- 4 × 6 = 24
Prime factorization expresses a number using only prime factors.
84 = 2 × 2 × 3 × 7 = 2² × 3 × 7
