Go to the editor The sum comes out to be 1. Equivalently, a perfect number is a number that is half the sum of all of its positive divisors (including itself) i.e. Turns left: 9 75 Your Guess Is Higher Than THe Right Guess! The first perfect number is 6. 65728 = 12^3 + 40^3 = 31^3 + 33^3 To convert an integer to binary divide the number by 2 until it becomes 0. 5 Lychrel seeds: [196, 879, 1997, 7059, 9999] Perfect number: In number system, 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. The first Catalan numbers for n = 0, 1, 2, 3, … are 1, 1, 2, 5, 14, 42, 132, 429, 1430, 4862, 16796, 58786, 208012, 742900, 2674440, 9694845, 35357670, 129644790, 477638700, 1767263190, 6564120420, 24466267020, 91482563640, 343059613650, 1289904147324, 4861946401452, 9. For example 3210, 7056, 8430709 are all duck numbers whereas 08237, 04309 are not. For example, 52 = 25, 62 = 36, 762 = 5776, and 8906252 = 793212890625, so 5, 6, 76 and 890625 are all automorphic numbers. Deficient number: In number theory, a deficient number is a number n for which the sum of divisors σ(n)<2n, or, equivalently, the sum of proper divisors (or aliquot sum) s(n) 9 and N < 50.
