Is 968 a deficient number?
No, 968 is not a deficient number: to be deficient, 968 should have been such that 968 is larger than the sum of its proper divisors, i.e., the divisors of 968 without 968 itself (that is 1 + 2 + 4 + 8 + 11 + 22 + 44 + 88 + 121 + 242 + 484 = 1 027).
In fact, 968 is an abundant number; 968 is strictly smaller than the sum of its proper divisors (that is 1 + 2 + 4 + 8 + 11 + 22 + 44 + 88 + 121 + 242 + 484 = 1 027). The smallest abundant number is 12.
