Question

Is 64 an abundant number?

Answer 1

64 is a deficient number

Answer 2

In number theory, an abundant number or excessive number is a number for which the sum of its proper divisors is greater than the number itself. The integer 12 is the first abundant number. Its proper divisors are 1, 2, 3, 4 and 6 for a total of 16. The amount by which the sum exceeds the number is the abundance. The number 12 has an abundance of 4,



Yes, 64 is a deficient number, that is to say 64 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 64 without 64 itself (that is 1 + 2 + 4 + 8 + 16 + 32 = 63).
