**Prime and Composite Numbers**

Factors: Factors are numbers that are multiplied

to get a product. In the multiplication sentence

3X7=21, the factors of 21 are 3 and 7.

**Prime numbers: **Numbers that have only 2 factors, 1

and itself, are called prime numbers. Example: the

number 5 is a prime number. You can not divide 5

evenly by 2, 3, or 4. You can only divide 5 evenly by

1 or itself.

**Composite numbers:** Numbers that have more than

2 factors are called composite numbers. The

number 6 is an example of a composite number.

You can divide six evenly by 1, 2, 3, and 6

The chart below shows some examples of prime and composite

numbers. The prime numbers are blue. The composite numbers are

Note: 1 is neither a prime number or a composite number.

Any whole number except 1 is either Prime or Composite.
