Just run this in some other than Pari/GP system x = 251; c = Fibonacci[x]; (*Solve[(((a*x+c-1)/((a*x-1)*x))^(-1))-(1/b)==0&&(x*a-1)*(b*x-1) ==c,{a,b},Integers]*) Solve[((a + b)^2 + 4*a*b*(c - 1)...

It is not so hard to write some simple code, like this (Pari GP) forprime(n=11,900,x=Mod(factorint(fibonacci(n)),n);print(n,lift(x))) and see, that posted above is true for all...
 Forum: Miscellaneous Math 2020-10-09, 06:52 Replies: 4 Views: 523 Posted By RMLabrador Factors of Fibonacci numbers Greetings. The factors of Fibonacci numbers: For prime p: F(p)=\prod_{i=1}^{m} (k_{i}\cdot p\pm 1) For an any n n=p_{1}^{t1}\cdot p_{2}^{t2}\cdot...\cdot p_{k}^{tk} F(n)=\prod_{i=1}^{m}...
