The divisors of 21 are: 1, 3, 7, 21.
48
6, 8, 10, 14, 15
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
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
It is 192.
The first number to have exactly 10 divisors is 48.
Oh, dude, the smallest number with 24 divisors is 60. It's like the VIP of numbers, with divisors lining up to hang out with it. So yeah, 60 is the cool kid on the block when it comes to having a bunch of divisors.
The smallest whole number that has exactly 6 distinct positive divisors is 12. The divisors of 12 are 1, 2, 3, 4, 6, and 12. These are the only positive integers that evenly divide 12, making it the smallest number with exactly 6 distinct positive divisors.
60. The number 60 has 12 divisors if you are counting the 1 and 60. The divisors (given as factor pairs) are 1, 60, 2, 30, 3, 20, 4, 15, 5, 12, 6, 10.
24 (1,2,3,4,6,8,12 & 24)
Yes.
The smallest number with exactly 14 divisors is 192. The divisors are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, and 192 itself.
72 is the second-smallest number with 12 factors. Its divisors are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The smallest number with 12 factors is 60. Its divisors are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.
I guess that would be the number 6.
I don't know if it's the smallest, but 94,143,178,827 has 24 factors.
The numbers are 6 (6,3,2,1) 8 (8,4,2,1) and 10 (10,5,2,1).
