prime number.noun
Mathematics.-.a prime number; a prime rate; a whole number not divisible without a remainder by any whole number other than itself and one
    An even number is any number divisible by 2.
    An odd number is any number not divisible by 2. 
    "A prime number is any integer greater than 1, that is divisible only by itself and 1. Examples of prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, etc.
    The only even prime number is 2. 
    Every integer greater than 1 that is not a prime number is the product of one and only one set of prime numbers. This theorem was first proved rigorously by the German mathematician Carl Friedrich Gauss. Given a number such as 14, the theorem states that it may be written uniquely as the product of primes, in this case, 14 = 2  7. Similarly, 50 = 2  5  5 = 2  52. By factoring numbers into their prime components, both their least common multiple and their greatest common divisor can be found." ...All rights reserved....Microsoft® Encarta® Encyclopedia 99.
