Definition
If n • m = k, then n and m are called factors or divisors of k, and k is said to be a multiple of n and m.
Remember that in the product 3 • 7 = 21, numbers 3 and 7 are called factors or divisors of 21. The product, which is 21, is called a multiple of 3 and 7. Likewise, in product 5 • 2 = 10, 5 and 2 are factors of 10, while 10 is called a multiple of 5 and 2.
When a number is multiplied by itself several times, you can write the product in exponential notation to simplify or shorten the expression.
