WebJan 5, 2012 · first Carmichael number : 561, 1105, 1729, 2465, 2821, 6601, ... Thus, 561 is a Carmichael number. In fact, it is the smallest Carmichael number. This means that the probability of success for a single iteration of the Fermat primality test is the probability that a randomly chosen element from 1 to 560 has a common factor with 561. This is ... WebTo give an example, 1729 is a Zeisel number with the constants a = 1 and b = 6, its factors being 7, 13 and 19, falling into the pattern ... so that every Carmichael number of the form (6n+1)(12n+1)(18n+1) is a Zeisel number.

WebThere exist infinitely many Carmichael numbers. Here are three examples: (1) Prove that 561 is a Carmichael number. (In fact, this is the smallest Carmichael number). Hint: use Fermat’s theorem for the prime factors of 561. (2) Prove that 1729 is a Carmichael number. (3) Prove that 2821 is a Carmichael number. (4) Show that if n = p1p2 ... WebNov 15, 2013 · UVa 10006: Carmichael numbers Process There’s a lot of math in this one. The problem is asking us to identify Carmichael numbers – non-primes that satisfy the equation a^n mod n = a for n from 2 to n – 1. It should be apparent that for large n, we won’t be able to store a^n in any data type (outside of BigInteger, but this is too slow).
