Answer:

A number is called perfect number if the sum of all its factors is equal to twice the number.

Step-by-step explanation:

All the factors of 28 are 1, 2, 4, 7, 14 and 28. Adding these we have, 1 + 2 + 4 + 7 + 14 + 28 = 56 = 2 × 28. The sum of the factors of 28 is equal to twice the number 28. A number for which sum of all its factors is equal to twice the number is called a perfect number.
