Is 76 an abundant deficient or perfect?

Answer 1

Abundant, deficient and perfect numbers are determined by the sum of the proper divisors (or factors) of a number, which excludes the number itself.

The factors of 76 are : 1,2,4,19,38,76 . . . after excluding the number itself the sum of the proper divisors is :-

1+2+4+19+38= 64

Deficient numbers occur when the sum of the proper divisors is less than the number itself.

As 64 is less that 76 then it is deficient.

Answer 2

76 is an abundant number. This means that the sum of its proper divisors (excluding itself) is greater than the number itself.
