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.
