Abstract

It is well known that a positive integer n is said to be near perfect number, if σ(n) = 2n+d where d is a proper divisor of n and function σ(n) is the sum of all positive divisors of n In this paper, we discuss some results concerning with near perfect numbers from known near perfect numbers.
