In number theory, the aliquot sum s(n) of a positive integer n is the sum of all proper divisors of n, that is, all divisors of n other than n itself.That is, It can be used to characterize the prime numbers, perfect numbers, "sociable numbers", deficient numbers, abundant numbers, and untouchable numbers, and to define the aliquot sequence of a number.

Determining the sum of a geometric sum when there is no sum
π Learn how to find the geometric sum of a series. A series is the sum of the terms of a sequence. A geometric series is the sum of the terms of a geometric sequence. The formula for the sum of n terms of a geometric sequence is given by Sn = a[(r^n - 1)/(r - 1)], where a is the first term

Amicable Pairs and Aliquot Cycles for Elliptic Curves
An amicable pair for an elliptic curve E/Q is a pair of primes (p,q) of good reduction for E satisfying #E(Fp) = q and #E(Fq) = p. Aliquot cycles are analogously defined longer cycles. Although rare for non-CM curves, amicable pairs are -- surprisingly -- relatively abundant in the CM case

Ever wondered what a partial sum is? The simple answer is that a partial sum is actually just the sum of part of a sequence. You can find a partial sum for both finite sequences and infinite sequences. When we talk about the sum of a finite sequence in general, weβre talking about the sum

Is there a limit to human longevity?
Is there a limit to the human lifespan? There are a few differing theories. Some argue that, yes, maximum lifespan is finite. Others think that with advances in medicine, the maximum could increase, but ultimately, our days are numbered. However, there is another possibility: the human li
