There are different types of Numbers in the number system.
Perfect Numbers are one of such types. The perfect number is a
positive number whose factors when added give back the number as
answer. The factors of the numbers are less than the number.
Some examples of perfect numbers are given below: 1. The factors
of number 6 are 1, 2 and 3. 1 + 2+ 3 = 6 So, 6 is a perfect
number. 2. The factors of 28 are 1, 2, 4, 7, and 14. 1 + 2 + 4 +
7 + 14 = 28 So, 28 is a perfect number. There are others such as
496, 8128 and many higher numbers. In a perfect number, the
product of its even factor and prime factor gives the number
itself. The perfect numbers are both even and odd. But there is
a confusion that whether a odd perfect number really do exist.
Mathematician found one but it gives an approximate answer. The
formula for finding even perfect number is given as, Let us
consider, p = 2 which is a prime number. -1) = 7 which is also a
prime number. The perfect numbers were used in ancient cultures
and religion of cert
