In natural numbers, which are one to infinity, that is, [1, 2, 3, 4, 5… infinity]; those numbers which can have only two factors, one is the number 1 and the other is the number itself, are called prime numbers. Simply put, those numbers which can be divided only by 1 and themselves are called prime numbers. So they only have two divisors.
For example:
3 (factors are 1 and 3);
7 (factors are 1 and 7), etc.
Composite numbers
All the numbers other than prime numbers, except 1, are composite numbers because they have more than two factors. That is, composite numbers can be divided by 1, themselves, and some other numbers also.
For example:
4 (factors are 1, 2 and 4);
20 (factors are 1, 2, 5 and 20), etc.
