How is 28 the perfect number?
First of all, to know if a number is abundant, deficient, or perfect, you need to know all the factors of your given number. The factors of 28 are 1,2,4,7,14, and 28. Add your proper factors -or the factors except itself- and determine if the sum of the proper factors is below (deficient), above (abundant), or the exact same amount (perfect). In this case, if you add the proper factors, it equals exactly 28. Because it is exact, it is perfect! =)
