WebMay 1, 2015 · At each recursive step, gcd will cut one of the arguments in half (at most). To see this, look at these two cases: If b >= a/2 then on the next step you'll have a' = b and b' < a/2 since the % operation will remove b or more from a. If b < a/2 then on the next step you'll have a' = b and b' < a/2 since the % operation can return at most b - 1. WebNov 7, 2015 · 1 Answer Sorted by: 2 You don't need the while loop if you are using recursion. Just do: public static int gcd (int a, int b) { if (a == b) { return a; } if (a > b) return gcd (a - b, b); return gcd (a, b - a); } By the way, while (a != b) is an infinite loop if it is reached.
