What number has more positive integral divisors 2008 or 2009?
Answer: 2008. d(n) is number of divisors of n. I give number of divisors and list them also. The divisors of n = 2008: 1, 2, 4, 8, 251, 502, 1004, 2008 d(2008) = 8 The divisors of n = 2009: 1, 7, 41, 49, 287, 2009 d(2009) = 6
Is 8 a perfect number?
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.

What is the smallest number with 8 divisors?
24 (1,2,3,4,6,8,12 & 24)
Is the number 24 abundant deficient or perfect?
The number 24 is classified as an abundant number. An abundant number is one where the sum of its proper divisors (excluding itself) is greater than the number itself. For 24, the proper divisors are 1, 2, 3, 4, 6, and 8, which sum to 24, making it equal to the number itself. Therefore, since the sum of the proper divisors equals 24, it is not perfect; however, the total sum of divisors including 24 is 60, which is greater than 24, confirming it as abundant.
