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! =)

You might be thinking of proper factors. Proper factors are just like the set of regular factors, except for 1 and the number itself.
The number 28 has 6 factors. Factors are numbers that can be multiplied together to get the original number. The factors of 28 are 1, 2, 4, 7, 14, and 28. This can be determined by finding all the pairs of numbers that multiply together to equal 28.

2, 4, 7, 8, 14, 28
2, 4, 7, 8, 14, 28
A perfect number is a number that is the sum of all its proper factors (that is all its factors excluding itself). The next perfect number after 28 is 496
That is one definition of the set of proper factors.
The largest proper factor of 16 is 8, and of 28 is 14. The largest common factor of the pair is 4.
2, 4, 7, 14, 28, 29, 58, 116, 203, 406
If you delete the 1, the rest of the numbers are the set of proper factors of 588.
2,2,7 are the factors of 28.
There aren't any numbers like that. You might be thinking of 28, which has a sum of all its factors equal to twice itself, making it a perfect number. Proper factors are a different set.
