Explanation
Factors of a number are all whole numbers that divide it evenly. Every number has at least two factors: 1 and itself. Prime numbers have exactly two factors. Composite numbers have more than two factors. Finding factors is useful in simplifying fractions and finding common denominators. The greatest common factor is the largest factor shared by two numbers.
Example
Factors of 12 are 1, 2, 3, 4, 6, and 12 because each divides 12 evenly.
