This will find all the perfect numbers, but it will take a long time to find the larger ones. For some reason, mine is a lot faster than the other ones. Took me around 20 mins and I finally got it Pls make this famous... ONLY 59 BLOCKS crazy I know. So what it does is that it makes a sequence starting from 1 and multiplies it by 2 each time. The program adds 1-n numbers from the sequence until the sum is a prime number. The prime number will then be multiplied by the largest number in the sum. It takes a long time since the program divides a number by every other number from the number before - 2. To check and see if it is a prime or not.
