# Composite Number

Composite number is a whole number that can be made by multiplying other whole numbers.

Example:

10 can be made by 5 × 2 so is a composite number.

## Not Composite number

5 = 1 × 5, Is not composite number because 1 × 5 isn’t using other whole numbers

7 = 2 × 3.5, Is not composite number because 3.5 isn’t whole numbers.

All whole numbers above 1 are either composite or prime.
