A Prime Number can be divided evenly only by 1 or itself. Hence, prime numbers have only 2 factors.
A composite number is a positive integer that has more than two different factors. The numbers 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, … are composite numbers because they are “composed” of other numbers.​​​​​​​
