Some observations:
next if $n =~ /0\d+/;
The \d+ is uneccesary in this line if you are just trying to skip numbers that contains zeroes. /0/ is adequate and infact, this regex misses numbers that end in zero such as 1120, 1130, etc.
$count++ if $num % $divider == 0;
The logic on this line is backwards, it should last if the result of % is non-zero, that way you will not have to check through all the number combinations if the first div fails.
foreach my $divider (2..9)
Finally, if you are looking for the highest common divisor, you should turn this loop around and start with 9, I would also move it inside the foreach (qw(01 02 13 23)) and do a last if you find a valid divisor for all 4 numbers again stopping you from checking too many combinations.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
