It is called a composite number because it has more than two factors
They are prime numbers
41 is a prime number. A whole number (integer) greater than one is called a "prime number" if it has no positive divisors/factors other than itself and one.
A whole number (integer) greater than one is called a "prime number" if it has no positive divisors other than itself and one. Three is one of those numbers.
A whole number (integer) greater than one is called a "prime number" if it has no positive divisors other than itself and one. 19 is one of those numbers.

39 is composite... --------------------- A prime number is a whole number greater than 1, whose only two whole-number factors are 1 and itself.
Two.A number with only two factors, one and itself, is called a prime number. The only even whole prime number is two. Your question implies that there is only one whole number greater than one which is prime, however, since odd numbers are whole numbers, and odd numbers (but not even) are prime, there are infinite prime numbers (since no one has checked each number to infinity to see if it's prime, and, obviously, never will, most assume that the list of prime whole numbers is not finite). Examples are 3, 5, and 13. 9 is an example of an odd number which is not prime.
