👉 A halation in mathematics is a concept used to describe the operation of calculating the greatest common divisor (GCD) of two numbers, or the least common multiple (LCM) of two integers. It is often encountered in number theory and related areas such as algebraic geometry, cryptography, and coding theory. In essence, a halation is an algorithm that takes two numbers as inputs and outputs their GCD or LCM respectively. The goal of a halation is to find the greatest common
