What’s the difference between prime and composite numbers?
Definition: A prime number is a whole number with exactly two integral divisors, 1 and itself. The number 1 is not a prime, since it has only one divisor. Definition: A composite number is a whole number with more than two integral divisors. So all whole numbers (except 0 and 1 ) are either prime or composite.

Why is the number 1 neither prime or composite?
A prime number is a whole number that only has two factors which are itself and one. A composite number has factors in addition to one and itself. The numbers 0 and 1 are neither prime nor composite. All even numbers are divisible by two and so all even numbers greater than two are composite numbers.
What number is not prime or composite?
Any number other than 1, which is not a prime number is a composite number. Thus a composite number is a number which has at least one factor other than 1 and itself.
Is 18 prime or composite number?

Is the number 21 prime or composite?
