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.
