Why is 20 a abundant?
Let S be the set of the positive divisors of 20, excluding 20. S = {1, 2, 4, 5, 10} The sum of all the elements of S = 1 + 2 + 4 + 5 + 10 = 22 > 20. Therefore, 20 is an abundant number.
Why is 20 a abundant number?
Let S be the set of the positive divisors of 20, excluding 20. S = {1, 2, 4, 5, 10} The sum of all the elements of S = 1 + 2 + 4 + 5 + 10 = 22 > 20. Therefore, 20 is an abundant number.

Is the number 20 a deficient number?
No; 20 is an abundant number. S = {1, 2, 4, 5, 10} is the set of all positive divisors of 20, excluding itself. The sum of these divisors = 1+2+4+5+10=22 which is greater than 20. Therefore 20 is an abundant number, not a deficient number. When the sum exceeds the number, the number is abundant. When the sum equals the number, the number is perfect. When the sum is less than the number, the number is deficient.
