**Definition **

A factor of a number is an exact divisor of that number i.e. the factor leaves remainder 0 when it divides the number.Multiples are what we get after multiplying the number by an integer (not a fraction). Watch Factors and Multiples Videos to learn more.

**Factors**

A factor of a number is an exact divisor of that number i.e. the factor leaves remainder 0 when it divides the number.

For example : 4 × 5 = 20

4 and 5 are factors of 20. We can also say that 20 is multiple of 4 and 5.

In 2 × 12 = 24,

2 and 12 are factors of 24.

**COMMON FACTORS** are: __Factors__ that two or more numbers have in __common . __The greatest factor that both numbers have in common.

**Finding Factors**

Start with 1 x the number. Try 2, 3, 4, etc. When you repeat your factors, cross out the repeat – you’re done at this point. If you get doubles (such as 4 x 4), then you’re done. Repeats or doubles let you know you’re done.

**Multiples**

A multiple is the product of a given whole number and another whole number.

Multiples form a skip counting pattern. For example:

5: 5, 10, 15, 20, 25, 30…

**Common Multiple : **

A multiple that 2 or more numbers have in common.

**Least Common Multiple : **

The smallest multiple that 2 or more numbers have in common.
