As of August 2024, the largest known certain Fibonacci prime is F 148091, with 30949 digits. It was proved prime by Laurent Facq et al. in September 2024. The largest known probable Fibonacci prime is F 6530879. It was found by Ryan Propper in August 2024. See more A Fibonacci prime is a Fibonacci number that is prime, a type of integer sequence prime. The first Fibonacci primes are (sequence A005478 in the OEIS): 2, 3, 5, 13, 89, 233, … See more A prime $${\displaystyle p}$$ divides $${\displaystyle F_{p-1}}$$ if and only if p is congruent to ±1 modulo 5, and p divides $${\displaystyle F_{p+1}}$$ if and only if it is congruent to ±2 … See more A prime p ≠ 2, 5 is called a Fibonacci–Wieferich prime or a Wall–Sun–Sun prime if $${\displaystyle p^{2}\mid F_{q},}$$ where See more • Lucas number See more It is not known whether there are infinitely many Fibonacci primes. With the indexing starting with F1 = F2 = 1, the first 34 indices n for which Fn is prime are (sequence A001605 in the OEIS): n = 3, 4, 5, 7, 11, 13, 17, 23, 29, 43, 47, 83, 131, 137, 359, 431, … See more For a prime p, the smallest index u > 0 such that Fu is divisible by p is called the rank of apparition (sometimes called Fibonacci entry point) of p and denoted a(p). The rank of … See more Because $${\displaystyle F_{a} F_{ab}}$$, we can divide any Fibonacci number $${\displaystyle F_{n}}$$ by the least common multiple of all $${\displaystyle F_{d}}$$ See more Every third number of the sequence is even (a multiple of ) and, more generally, every kth number of the sequence is a multiple of Fk. Thus the Fibonacci sequence is an example of a divisibility sequence. In fact, the Fibonacci sequence satisfies the stronger divisibility property In particular, any three consecutive Fibonacci numbers are pairwise coprime because both and . That is,
