## What is Euclid’s Algorithm?

Euclid’s Algorithm is a fundamental algorithm in number theory for finding the greatest common divisor (GCD) of two integers. It is named after the ancient Greek mathematician Euclid, who described it in his work “Elements” around 300 BCE. The GCD of two integers is the largest positive integer that divides both of them without leaving a remainder.

The basic idea of Euclid’s Algorithm is to repeatedly replace the larger of two numbers with the remainder of their division until the remainder becomes zero. At that point, the last non-zero remainder is the GCD of the two numbers.

## All Formulae Related to Euclid’s Algorithm

Euclid’s Algorithm is a process for finding the greatest common divisor (GCD) of two positive integers a and b. It does not involve explicit mathematical formulas but is based on a recursive process. Here are the key steps involved in Euclid’s Algorithm without using specific formulas:

1. Given two positive integers, a and b, where a > b:
2. Divide a by b to find the quotient q and remainder r (a = bq + r).
3. If r is equal to zero, then the GCD of a and b is b.
4. If r is not zero, replace a with b and b with r, and repeat the process from step 2 until r becomes zero.

The GCD can be found by repeatedly applying this process until the remainder becomes zero, at which point the last non-zero remainder is the GCD of the two numbers.

Euclid’s Algorithm is more of a recursive algorithm than a set of mathematical formulas, making it a simple and efficient way to find the GCD of two numbers.
