Every number has a unique set of numbers that divide evenly into it; all other numbers leave a remainder. These numbers are called the factors. Additionally, each number has a set of numbers that can be obtained by multiplying the number a certain number of times. These numbers are called the multiples. Factors and multiples have many different applications in arithmetic and algebra.
