Sum of 24's divisors: 60.
A perfect number equals the sum of its proper divisors. A deficient number is greater than the sum of its proper divisors. An abundant number is less than the sum of its proper divisors. Proper divisors of a number do not include the number itself.
The sum is 195.
its 217
A perfect number is the sum of its divisors; for example 6 is a perfect number because the sum of its divisors is 6 (1 + 2 + 3). The sum of the divisors of 8 is 7 (1 + 2 + 4), so 8 is not a perfect number.
Because the sum of its proper divisors is greater than 36.
Sum of divisors: 1,392.
Sum of divisors: 980.
Sum of divisors: 1728.
Sum of divisors of 130 = 252.
Sum of 24's divisors: 60.
Sum of 150's divisors = 372.
The sum of its proper divisors 1, 2, 3, 4, 6, 9, 12, 18 is greater than 36.
100,000 has 36 divisors.
A perfect number equals the sum of its proper divisors. A deficient number is greater than the sum of its proper divisors. An abundant number is less than the sum of its proper divisors. Proper divisors of a number do not include the number itself.
The sum is 195.
