The Twenty-second Fermat Number Is Composite
We have shown by machine proof that F22 = 22 +1 is composite. In addition, we reenacted Young and Buell's 1988 resolution of F20 as composite, finding agreement with their final Selfridge-Hurwitz residues. We also resolved the character of all extant cofactors of Fn , n < 22, finding no new primes, and ruling out prime powers.
متن کاملThe twenty-fourth Fermat number is composite
We have shown by machine proof that F24 = 22 24+1 is composite. The rigorous Pépin primality test was performed using independently developed programs running simultaneously on two different, physically separated processors. Each program employed a floating-point, FFT-based discrete weighted transform (DWT) to effect multiplication modulo F24. The final, respective Pépin residues obtained by th...
متن کاملThe Factorization of the Ninth Fermat Number
In this paper we exhibit the full prime factorization of the ninth Fermât number Fg = 2512 + 1 . It is the product of three prime factors that have 7, 49, and 99 decimal digits. We found the two largest prime factors by means of the number field sieve, which is a factoring algorithm that depends on arithmetic in an algebraic number field. In the present case, the number field used was Q(v^2). T...
متن کاملFactorization of the tenth Fermat number
We describe the complete factorization of the tenth Fermat number F10 by the elliptic curve method (ECM). F10 is a product of four prime factors with 8, 10, 40 and 252 decimal digits. The 40-digit factor was found after about 140 Mflop-years of computation. We also discuss the complete factorization of other Fermat numbers by ECM, and summarize the factorizations
متن کاملOn the Number of Solutions to the Generalized Fermat Equation
We discuss the maximum number of distinct non-trivial solutions that a generalized Fermat equation Ax n + By n = Cz n might possibly have. The abc-conjecture implies that it can never have more than two solutions once n > n 0 (independent of A; B;C); and that it has no solutions for xed A; B; C once n > n A;B;C. On the other hand for any set of pairwise coprime integers p 1 ; p 2 ; :: : ; p k ,...
