The sum is 195.
Sum of divisors = 91.
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.
none
lets see...prime factorization of 100, 2,2,5,5 so divisors are 2,4,10,20,25,50 so the sum is 111 unless you want to include 1 and 100 then the sum is 212
The sum is 195.
Because the sum of its proper divisors is greater than 100.
Sum of divisors = 91.
Sum of divisors: 1,392.
Sum of divisors: 980.
Sum of divisors: 1728.
60
Sum of divisors of 130 = 252.
Sum of 24's divisors: 60.
Sum of 150's divisors = 372.
