How to find Sum of Reciprocals of given numbers and their product

WebThe convergence to Brun's constant. In number theory, Brun's theorem states that the sum of the reciprocals of the twin primes (pairs of prime numbers which differ by 2) converges to a finite value known as Brun's constant, usually denoted by B2 (sequence A065421 in the OEIS ). Brun's theorem was proved by Viggo Brun in 1919, and it has ... Web23 Aug 2014 · Baffling behaviour when summing reciprocals.

Web24 Mar 2024 · In 1932, Erdős proved that the sum of the reciprocals of any number of equally spaced integers is never a reciprocal. Nontrivial sets of integers are known whose reciprocals sum to small integers. For example, there exists a set of 366 positive integers (with maximum 992) whose sum of reciprocals is exactly 2 (Mackenzie 1997; Martin). A ... The sum of the reciprocals of all prime numbers diverges; that is: This was proved by Leonhard Euler in 1737, and strengthens Euclid's 3rd-century-BC result that there are infinitely many prime numbers and Nicole Oresme's 14th-century proof of the divergence of the sum of the reciprocals of the integers (harmonic series).

WebOne way to interpret this fact is that there must be a “lot” of primes—well, of course there are an infinite number of them, but not every infinite set of natural numbers has a reciprocal sum which diverges (for instance, take the powers of 2).
