<?php
function findBestFactors($Value, $GroupSize = INF)
        {
        foreach(range(min($GroupSize, ceil(sqrt($Value))), 1) as $Factor)
                {
                if (0 == ($Value % $Factor))
                        {
                        return array($Factor, $Value / $Factor);
                        }
                }
        }

list($Groups, $Size) = findBestFactors($argv[1], isset($argv[2]) ?
$argv[2] : INF);
echo "$Groups groups of $Size";
?>

Supply a value and an optional maximum group size.
