SUMMARY

The Fibonacci sequence is confirmed as a divisibility sequence through the property that the greatest common divisor (gcd) of two Fibonacci numbers can be expressed as gcd(Fm, Fn) = Fgcd(m,n). This relationship is foundational in number theory and can be proven using the Euclidean algorithm. The discussion references a Stack Exchange post that elaborates on modular results related to Fibonacci numbers, providing a deeper understanding of their divisibility properties.

PREREQUISITES
  • Understanding of Fibonacci numbers and their properties
  • Familiarity with the concept of greatest common divisor (gcd)
  • Basic knowledge of the Euclidean algorithm
  • Exposure to modular arithmetic
NEXT STEPS
  • Study the proof of gcd(Fm, Fn) = Fgcd(m,n) in detail
  • Explore the Euclidean algorithm and its applications in number theory
  • Investigate modular arithmetic and its relevance to Fibonacci numbers
  • Review additional properties of divisibility sequences in mathematics
USEFUL FOR

Mathematicians, students studying number theory, and anyone interested in the properties of Fibonacci numbers and divisibility sequences.

I wanted to prove that the Fibonacci sequence is a divisibility sequence, but I don't even know how to prove it.
all I know is that $$gcd\left({F}_{m},{F}_{n}\right)={F}_{gcd\left(m,n\right)}$$ and I should somehow use the Euclidean algorithm?
