8128 / 2 = 2^6 x 127
8128 / 1 = 8128
8128 / 2 = 4064
8128 / 4 = 2032
8128 / 8 = 1016
8128 / 16 = 508
8128 / 32 = 254
8128 / 64 = 127
1 + 2 + 4 + 8 + 16 + 32 + 64 + 127 + 254 + 508 + 1016 + 2032 + 4064 + 8128 = 16252
abundant since sum of divisors is 16256
Sum of divisors: 1728.
Sum of divisors: 1,392.
Sum of divisors: 980.
Sum of divisors = 91.
Sum of divisors of 130 = 252.
Add them together.
Sum of 24's divisors: 60.
Sum of 150's divisors = 372.
A number is considered perfect if it is equal to the sum of all its positive factors/divisors, excluding itself. These are the first few perfect numbers: * 6 * 28 * 496 * 8128 * 33550336 * 8589869056A perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself. An example 1+2+3=6 and 1x2x3=6
A perfect number is a number which is the sum of it's positive proper divisors. 214 has divisors: 1, 2, 107 1 + 2 + 107 = 110 != 214 Thus 214 is not a perfect number The first 4 perfect numbers are: 6, 28, 496 and 8128.
How am i suppose to know? :-) please look at some other website cause none is answering this question
