Fermat Numbers
sites.millersville.edu › fermat-numbersA 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-

wstein.org › edu › 20103 Geometric Interpretation of Fermat Numbers As Gauss’s theorem suggests, Fermat numbers might be closely related to some of the problems in Geometry. It is hence useful if we can understand what they mean geometrically. A Fermat number Fn = 2 6 Ù+ 1 (for n ≥ 1) can be thought of as a square whose side length is

Number Theory: Fermat’s Last Theorem
web.nmsu.edu › ~davidp › history166 4. Number Theory: Fermat’s Last Theorem Fermat then broadened his investigation of primality to numbers of the form an + 1, for integers a and n. A letter to Mersenne, dated Christmas Day 1640, suggests that he found a proof that such a number could be prime only if a is even and n is a power of 2 (Exercise 4.5). Based on his
FERMAT’S LITTLE THEOREM

Background and History of Fermat’s Little Theorem Fermat’s Little Theorem is stated as follows: If p is a prime number and a is any other natural number not divisible by p, then the number is divisible by p. However, some people state Fermat’s Little Theorem as,
