Here's how to compute the least common multiple of an array of integers: function gcd($a,$b) { while($b) { $temp=$a%$b; $a=$b; $b=$temp; } return $a; } function lcm($a, $b) { return $a*$b/gcd($a,$b); } $n=array(3,5,7,9,15); echo array_reduce($n,"lcm"); -- David -- http://www.php.net/manual/en/ref.math.php http://master.php.net/manage/user-notes.php?action=edit+21959 http://master.php.net/manage/user-notes.php?action=delete+21959 http://master.php.net/manage/user-notes.php?action=reject+21959
