1. Mathematicians define a perfect number as positive integer that is the sum of it's positive divisors excluding the number itself. Well, where injuries and illnesses are concerned, zero is the perfect number. perfect number. A positive integer that equals the sum of all of its divisors other than itself. In mathematics an automorphic number (sometimes referred to as a circular number ) is a number whose square "ends" in the same digits as the number itself. For example, 5 2 = 2 5 , 6 2 = 3 6 , 76 2 = 57 76 , and 890625 2 = 793212 890625 , so 5, 6, 76 and 890625 are all automorphic numbers. A prime number (or a prime ) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A prime number (or a prime ) is a natural number greater than 1 that has no positive divisors other than 1 and itself. .
