Fermat primes proof

WebThe proof of Fermat’s Last Theorem for n = 4 can be given with elementary methods. This proof is often attributed to Fermat himself, although no records of it exist, because he posed this case as a challenge to others [7]. The proof attributed to Fermat relies on a well known characterization of Pythagorean triples given in the following lemma. WebSince every integer n≥3 is divisible either by an odd prime or by 4, the result of Fermat allowed one to reduce the study of Fermat’s equation to the case where n= ‘is an odd …

WebA Fermat primeis a Fermat number which is prime. It is an open question as to whether there are infinitely many Fermat primes. Surprisingly, Fermat primes arise in deciding whether a regular n-gon (a convex polygon with nequal sides) can be constructed with a compass and a straightedge. Gauss showed that a regular n-gon is con- WebKummer shows that all primes up to 37 are regular but 37 is not regular as 37 divides the numerator of B 32 B_{32} B 3 2 . The only primes less than 100 which are not regular are 37, 59 and 67.More powerful techniques were used to prove Fermat's Last Theorem for these numbers. This work was done and continued to larger numbers by Kummer, …

WebIn number theory, Euler's theorem (also known as the Fermat–Euler theorem or Euler's totient theorem) states that, if n and a are coprime positive integers, and is Euler's totient function, then a raised to the power is congruent to 1 modulo n; that is Generalized Fermat primes. Because of the ease of proving their primality, generalized Fermat primes have become in recent years a topic for research within the field of number theory. Many of the largest known primes today are generalized Fermat primes.
