# Composite Number - Definition with Examples

## Let's learn!

**What are composite numbers?**

In math, composite numbers can be defined as the whole numbers that have more than two factors.

Whole numbers that are not prime are composite numbers, because they are divisible by more than two numbers.

For example, 4, 6, 8, 9 and 10 are the first few composite numbers.

Here’s a list of all the composite numbers up to 100, marked in yellow.

## Let's do it!

Ask your children to identify the numbers you say as composite or prime. You can further ask them to find the factors of the composite numbers they identified.
