perfect numbers

Well recently I have had some extra time so I decided to look up perfect numbers.

Perfect numbers are number that, when you add up all of the factors, not including the number, you make that number.

You probably still dont understand. For example, the first perfect number is 6. So, the factors of 6 are: 1,2,3, and 6. but you take away the 6, because it is the number. That leaves, 1, 2, and 3. 1 plus 2 plus 3 equals 6. beacuse it does, that makes it a perfect number.

One more interesting fact about them is that the last number of each perfect number is either, from 6 to 8.

The First ten perfect numbers:

1                                                                                                                                6

2                                                                                                                              28

3                                                                                                                            496

4                                                                                                                         8,128

5                                                                                                                33,550,336

6                                                                                                           8,589,869,056

7                                                                                                       137,438,691,328

8                                                                                       2,305,843,008,139952,128

9                                            2,658,455,991,569,831,744,654,692,615,953,842,176
