Repunit R49081 is a probable prime
The Repunit R49081 = (1049081 − 1)/9 is a probable prime. In order to prove primality R49080 must be approximately 33.3% factored. The status of this factorization is included. Repunits are numbers of the form Rn = (10 − 1)/9. Considerable computer time has been spent factoring repunits, creating interesting primes based on the characteristics of repunits, and searching for repunit primes. One ...
متن کاملA Rationality Condition for the Existence of Odd Perfect Numbers
A rationality condition for the existence of odd perfect numbers is used to derive an upper bound for the density of odd integers such that σ(N) could be equal to 2N, where N belongs to a fixed interval with a lower limit greater than 10300. The rationality of the square root expression consisting of a product of repunits multiplied by twice the base of one of the repunits depends on the charac...
متن کاملRFSC 04-01 Revised A PROOF OF THE ODD PERFECT NUMBER CONJECTURE
It is sufficient to prove that there is an excess of prime factors in the product of repunits with odd prime bases defined by the sum of divisors of the integer N = (4k+1) ∏l i=1 q 2αi i to establish that there do not exist any odd integers with equality between σ(N) and 2N. The existence of distinct prime divisors in the repunits in σ(N) follows from a theorem on the primitive divisors of the ...

متن کاملFactoring Generalized Repunits
Twenty-five years ago, W. M. Snyder extended the notion of a repunit Rn to one in which for some positive integer b, Rn(b) has a b-adic expansion consisting of only ones. He then applied algebraic number theory in order to determine the pairs of integers under which Rn(b) has a prime divisor congruent to 1 modulo n. In this paper, we show how Snyder’s theorem follows from existing theory pertai...
