33550336 = 212*8191
So its factors are of the form 2m and 2n*8191 where 0 ≤ m,n ≤ 12.
Their sum is (1 + 8191)*(20 + 21 + 22 + ... + 212) = 8192*(213 - 1)/(2 -1) = 67100672
This includes the factor 33550336 itself, so the sum of the proper factors is 67100672 - 33550336 = 33550336. Therefore the number is perfect.
