**In math terms, a number's multiples are the product of that number and another whole number.** For instance, multiples of seven include seven, 14 and 21 because these numbers result when seven is multiplied by 1, 2 and 3.

All multiples of 10 end in a zero because 10 multiplied by any number has a zero at the end. All multiples of five end in five or zero, and all multiples of two end in an even number. Every number is a multiple of one, and the least common multiple of two numbers is the smallest number evenly divisible by both of the numbers.
