The Fibonacci numbers

* The Fibonacci series
* The first 300 Fibonacci numbers, factored
.. and, if you want numbers beyond the 300-th:-
* Fibonacci Numbers 301-500, not factorised)
* There is a complete list of all Fibonacci numbers and their factors up to the 1000-th Fibonacci and 1000-th Lucas numbers and partial results beyond that on Blair Kelly's Fibonacci Factors pages
The Fibonacci series
is formed by adding the latest two numbers to get the next one, starting from 0 and 1:
0 1 --the series starts like this.
0+1=1 so the series is now
0 1 1
1+1=2 so the series continues...
0 1 1 2 and the next term is
1+2=3 so we now have
0 1 1 2 3 and it continues as follows ...
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, ...

It can find Fib(2000) exactly - all 418 digits - in about 50 seconds on an Apple Macintosh PowerBook G3 series 266MHz computer.
It can find the first few digits of even higher numbers, instantly, such as the twenty-millionth Fibonacci number, F(20,000,000) which begins 285439828... and has over 4 million digits!
The (recurrence) formula for these Fibonacci numbers is:
F(0)=0, F(1)=1, F(n)=F(n-1)+F(n-2) for n>1.
and an explicit formula for F(n) just in terms of n (not previous terms) is given on a later page.
The first 300 Fibonacci numbers, completely factorised
If a number has no factors except 1 and itself, then it is called a prime number.
The factorisations here are produced by Maple with the command
with(combinat);
seq(lprint(n,`:`,fibonacci(n),`=`,ifactor(fibonacci(n))),n=1..100);
and then reformatted slightly.
Every Fibonacci number bigger than 1 [except F(6)=8 and F(12)=144] has at least one prime factor that is not a factor of any earlier Fibonacci number. Those factors are shown like this.
Index numbers that are prime are shown like this.
