Example, σ (11) = 1 + 11 = 12 and σ (15) = 1 + 3 + 5 + 15 = 24. Perfect Number Definition 2. The number N is said to be perfect if σ (N) = 2N. When σ (N) < 2N, we say N is deficient; when σ (N) > 2N, we say N is abundant. The definition of perfect number is equivalent to saying that the sum of the proper (or aliquot) divisors of N is equal ...The result of multiplying an integer (not a fraction) by itself.
