What is a composite number?
A composite number is a natural number that has more than two factors. In other words, it is a number that can be divided exactly by numbers other than 1 and itself.
Examples:
4 = 1, 2, 4
6 = 1, 2, 3, 6
12 = 1, 2, 3, 4, 6, 12
All composite numbers can be expressed as the product of smaller natural numbers. The number 1 is neither prime nor composite, while 2 is the smallest prime number.
