code of euclid's algorithm code example

Example 1: euclid algorithm

int Euclid(int a, int b)
{
    int r;
    while(b != 0) 
    {
         r = a % b;
         a = b; 
         b = r; 
    }
    return a; 
}

Example 2: euclid algorithm

function mcd($a,$b) {
	while($b) list($a,$b)=array($b,$a%$b);
	return $a;
}
