WHAT DOES PERFECT NUMBER MEAN IN ENGLISH?

Perfect number

In number theory, a perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive divisors excluding the number itself. Equivalently, a perfect number is a number that is half the sum of all of its positive divisors i.e. σ1 = 2n. This definition is ancient, appearing as early as Euclid's Elements where it is called τέλειος ἀριθμός. Euclid also proved a formation rule whereby is an even perfect number whenever is what is now called a Mersenne prime. Much later, Euler proved that all even perfect numbers are of this form. It is not known whether there are any odd perfect numbers, nor if infinitely many perfect numbers exist.
