Factors are the positive whole numbers that divide a given whole number evenly, so the quotient is also a whole number; equivalently, they form complete factor pairs whose product is the number, including 1 and the number itself. This understanding applies especially to whole numbers within 100, distinguishes factors from multiples, and supports recognizing prime numbers; negative, fractional, and algebraic factors are beyond this scope.
Factors are positive whole numbers that divide a number evenly, with no remainder. Factors always come in pairs that multiply to make the given number.
Example: Find all the factors of .
Start with :
Try the next numbers:
The factor pairs are:
So, the factors of are:
Remember: factors divide evenly into a number. Multiples are the numbers you get when you multiply a number by
