Answer 2

Answer:

2 perfect numbers...

There are around 51 known perfect numbers. There are only 2 perfect numbers from 1 to 100 which are 6 and 28.

Step-by-step explanation:

A number is called a perfect number if by adding all the positive divisors of the number (except itself), the result is the number itself. 6 is the first perfect number. Its divisors (other than the number itself: 6) are 1, 2, and 3 and 1 + 2 + 3 equals 6. Other perfect numbers include 28, 496 and 8128.
