Prime factors are 2, 2, 2, 2, 2, 2, 127
(Other) factors are combinations, i.e.
2 x 2 = 4
2 x 127 = 254
2 x 2 x 2 = 8
2 x 2 x 127 = 508
2 x 2 x 2 x 2 = 16
2 x 2 x 2 x 127 = 1016
2 x 2 x 2 x 2 x 2 = 32
2 x 2 x 2 x 2 x 127 = 2032
2 x 2 x 2 x 2 x 2 x 2 = 64
2 x 2 x 2 x 2 x 2 x 127 = 4064
You get 8128!!! It is PERFECT!!
8128 = 26*127

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
There is a formula to calculate even perfect numbers, 2p-1(2p - 1) where p is a prime number. When p = 7 then 26(27 - 1) = 64 x 127 = 8128 So 8128 is the 4th perfect number. (The other three occur when p = 2, 3 and 5)
8128 They're known as perfect numbers.
Prime factors are factors that are also prime numbers.
