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 ...
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!
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.
