Formula:
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.
A composite number is a natural number greater than 1 that is not prime (i.e., it has at least one divisor other than 1 and itself).
The numbers 0 and 1 are neither prime nor composite.
