# Prime numbers under 10,000

## Using CSS counters!

A prime number is a whole number greater than **one **(1) that cannot be divided by any whole number except itself and the number **1**.

Legend:

A natural number greater than **1** that is not prime is called a composite number. For example, **5** is prime because the only ways of writing it as a product, **1** × **5** or **5** × **1**, involve **5** itself. The smallest composite number is **4**, because **2** x **2** = **4**. **1** is not a composite number. Every other number is a prime number. The smallest prime number is **2**. The next prime numbers are **3**, **5**, **7**, **11**, and **13**. There is no largest prime number.
