A prime number has only two factors, itself and one. A composite number has at least three factors, and sometimes a lot more.
What isn’t a composite number?
A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself. Likewise, the integers 2 and 3 are not composite numbers because each of them can only be divided by one and itself.
Is 81 prime or composite?
