// PHP program to find LCM of two numbers
// Recursive function to
// return gcd of a and b
function gcd( $a, $b)
{
if ($a == 0)
return $b;
return gcd($b % $a, $a);
}
// Function to return LCM
// of two numbers
function lcm( $a, $b)
{
return ($a * $b) / gcd($a, $b);
}
// Driver Code
$a = 15;
$b = 20;
echo "LCM of ",$a, " and " ,$b, " is ", lcm($a, $b);
