If your device is bored at night while you are sleeping, give it the attached project to work on while you are sleeping and see how far it got by the time that you get up in the morning. Finding just the first 5 perfect numbers. The first 4 can be found in less than 4 seconds. As for the fifth....well, that is going to take some time. Perfect numbers are numbers where the factors of the number (excluding the number itself) add to the number: eg factors of 6 are 1, 2, and 3 = 6 (therefore 6 is a perfect number) eg factors of 28 are 1, 2, 4, 7, 14 = 28 (therefore 28 is a perfect number) etc My device will take approximately 29 hours to calculate the 5th perfect number (it being 33,550,336) The last discovered perfect number has 34,850,340 digits. It was discovered in 2013 by Cooper, Woltman, Kurowski, et al.
