👉 A megalo- is a type of mathematical operation used to find the greatest common divisor (GCD) of two integers. It is also known as the Euclidean algorithm or the extended Euclidean algorithm. The GCD of two numbers \(a\) and \(b\) is the largest positive integer that divides both of them without leaving a remainder. For example, the GCD of 12 and 36 is 12 because 12 is the largest number that divides both
