Factors and Multiples

are parts of numbers that, multiplied together, give a larger number.
Every number has at least two factors, one and the number itself. On the other hand,

are numbers where the same number is repeated, as if you were
counting by that number. For example, the multiples of 2 start with 2 and are: 2,
4, 6, 8, 10 . . . and so on. Each additional number is a multiple of 2.

Factors and multiples are especially important in working with expanding and reducing
fractions, as well as finding patterns in numbers. Finding the greatest common
least common multiple
, and
prime factors
of a number are important skills you will learn in
this section.
