Problem statement and Explanation : https://en.wikipedia.org/wiki/Euclidean_algorithm

In this method, we have followed the iterative approach to first
find a minimum of both numbers and go to the next step.

* @param {Number} arg2 second argument for gcd
* @returns return a `gcd` value of both number.
