Is the number 21 abundant or deficient or perfect?
It is deficient: It's only proper divisors are 1, 3, and 7, which sums to 11, which is less than 21.
What is the smallest number with 10 divisors?
48
Is the number 14 a abundant perfect or deficient number?
14 is deficient. It is less than the sum of it's divisors. In mathematics, a deficient number or defective number is a number n for which σ(n) < 2n. Here σ(n) is the sum-of-divisors function: the sum of all positive divisors of n, including n itself Proof.. divisors of 14 are 1,2, and 7 and 14. Now, 2n=28 and and the sum the all the divisors including 14 is 24<28
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
What are the divisors of 6?
the divisors of 6 are: 1,2,3, and 6.
