<p>There are two main<a>types of numbers</a>-<a>prime numbers</a>and<a>composite numbers</a>, determined by the number of<a>factors</a>they have. A prime number is a<a>natural number</a>that is divisible only by 1 and itself. For example, 3 is a prime number because it is divisible by 1 and itself.</p>
