Perfect numbers are numbers whose proper divisors (the divisors except for the number itself) add up to the number itself. The first four perfect numbers, 6, 28, 496, and 8128 have been known since ancient times. 6 = 1 + 2 + 3 28 = 1 + 2 + 4 + 7 + 14 At least 46 perfect numbers had been discovered before the end of 2008. A link to a listing of perfect numbers is provided below. perfect nos. follow the mathematical formula: 2^(p-1)*[2^(p)-1]
6 and 28
The two numbers between 5 and 20 that are almost perfect are 6 and 28. An almost perfect number is a number that equals the sum of its proper divisors, excluding itself. The proper divisors of 6 are 1, 2, and 3, which sum up to 6. Similarly, the proper divisors of 28 are 1, 2, 4, 7, and 14, which sum up to 28.
