<p>A<a>composite number</a>has more than two factors. For example, 6 is a composite number because it is divisible by 1, 2, 3, and 6. Some properties<a>of</a>prime numbers include: Prime numbers are greater than 1. 2 is the only even prime number. Prime numbers have only two factors: 1 and the number itself. Any two distinct prime numbers are co-prime, as they only share 1 as a<a>common factor</a>.</p>
