This is the largest known Fibonacci number that's also prime, which is 21925 digits long and was proved prime by Mathew Steine and Bouk de Water in 2015.

Are there infinitely many prime Fibonacci numbers?

Probably yes. Not proved yet. However, it was proved that the only Fibonacci numbers that are also members of the set of twin primes are 3, 5, and 13. A twin prime is a prime number that is either 2 less or 2 more than another prime number. E.g. (11, 13)

More interestingly: 1) Every 3rd Fibonacci number is even 2) Fn divides Fmn ∴ ∀ Fibonacci prime must have prime index (converse isn't true) Exception F4=3 Largest proven Fibonacci prime = F104911 (104911 is prime) Largest probable Fibonacci prime = F3244369 (3244369 is prime)

How do you prove a number is prime

If a number has no prime divisors smaller than its root, it kust be prime. For example, the square root of 17 is a little over 4, so if you show 17/2 isn't a whole number, and that 17/3 isn't a whole number, 17 must be prime

Do you know the Fibonacci sequence 1,1,2, 3,5,8, 13, 21 ... ? Do you know what a prime number is (2,3,5,7,11,13,17,19)? OP wrote F_n to mean the nth Fibonacci number. For example, F_6 = 8. The claim then is that F_104911 is prime and this is the largest Fib prime we know.

Interestingly this is also the number to call in Siena for prime, rich pasta Alfredo and spaghetti al forno. Fibonacci Kitchen is where you get a meal like Mama used to make. If your Mama was a mathematician.
