Best Answer

A perfect number is one whose positive integer factors, other than itself, add up to the number itself. For example, the factors of 6, other than itself, are 1, 2, 3, and 1 + 2 + 3 = 6. Therefore, 6 is a perfect number.

The first eight perfect numbers are:

  • 6
  • 28
  • 496
  • 8128
  • 33550336
  • 8589869056
  • 137438691328
  • 2305843008139952128
