The first Fermat number known to be composite is F 5, which is equal to 4,294,967,297. The prime factorizations of this number are 641 and 6,700,417. The prime factorizations of this number are 641 and 6,700,417.

The only known Fermat primes are the first five Fermat numbers: F 0 =3, F 1 =5, F 2 =17, F 3 =257, and F 4 =65537. A simple heuristic shows that it is likely that these are the only Fermat primes (though many folks like Eisenstein thought otherwise). In 1732 Euler discovered 641 divides F 5.

Fermat first conjectured that all the numbers in the form of 2 + 1 are primes. However, in. 1732, Leonhard Euler refuted this claim by showing ...

There are two definitions of the Fermat number. The less common is a number of the form 2^n+1 obtained by setting x=1 in a Fermat polynomial, the first few of which are 3, 5, 9, 17, 33, ... (OEIS A000051). The much more commonly encountered Fermat numbers are a special case, given by the binomial number of the form F_n=2^(2^n)+1.

What is the first Fermat number? The first few Fermat numbers are: 3, 5, 17, 257, 65537, 4294967297, 18446744073709551617, (sequence A000215 in the OEIS). Why is Fermat famous? Pierre de Fermat, (born August 17, 1601, Beaumont-de-Lomagne, France—died January 12, 1665, Castres), French mathematician who is often called the founder of the modern theory of …

Fermat thought that all the Fn were prime. The first five are: F0 = 3, f1 = 5, F2 = 17, F3 = 257, F4 = 65537. However ...

The first few Fermat numbers are: 3, 5, 17, 257, 65537, 4294967297, 18446744073709551617, ... (sequence A000215 in the OEIS ). If 2 k + 1 is prime and k > 0, then k must be a power of 2, so 2 k + 1 is a Fermat number; such primes are called Fermat primes.

where n is a nonnegative integer. The first nine Fermat numbers are (sequence A000215 in the OEIS): ... As of 2007, only the first 12 Fermat numbers have been ...

The numbers grow very rapidly since each Fermat number is obtained by raising 2 to a power of 2. The first several terms are 3, 5, 17, 257, ...

In mathematics, a Fermat number, named after Pierre de Fermat, who first studied them, is a positive integer of the form where n is a non-negative integer. The first few Fermat numbers are: 3, 5, 17, 257, 65537, 4294967297, 18446744073709551617, ... (sequence A000215 in the OEIS).If 2 + 1 is primeand k > 0, then k must be a power of 2, so 2 + 1 is a Fermat number; such primes …
