<p>You are given an integer array <code>nums</code>.</p>

<p>The <strong>factor score</strong> of an array is defined as the <em>product</em> of the LCM and GCD of all elements of that array.</p>

<p>Return the <strong>maximum factor score</strong> of <code>nums</code> after removing <strong>at most</strong> one element from it.</p>

<p><strong>Note</strong> that <em>both</em> the <span data-keyword="lcm-function">LCM</span> and <span data-keyword="gcd-function">GCD</span> of a single number are the number itself, and the <em>factor score</em> of an <strong>empty</strong> array is 0.</p>

<p>&nbsp;</p>
<p><strong class="example">Example 1:</strong></p>

<div class="example-block">
<p><strong>Input:</strong> <span class="example-io">nums = [2,4,8,16]</span></p>

<p><strong>Output:</strong> <span class="example-io">64</span></p>

<p><strong>Explanation:</strong></p>

<p>On removing 2, the GCD of the rest of the elements is 4 while the LCM is 16, which gives a maximum factor score of <code>4 * 16 = 64</code>.</p>
</div>

<p><strong class="example">Example 2:</strong></p>

<div class="example-block">
<p><strong>Input:</strong> <span class="example-io">nums = [1,2,3,4,5]</span></p>

<p><strong>Output:</strong> <span class="example-io">60</span></p>

<p><strong>Explanation:</strong></p>

<p>The maximum factor score of 60 can be obtained without removing any elements.</p>
</div>

<p><strong class="example">Example 3:</strong></p>

<div class="example-block">
<p><strong>Input:</strong> <span class="example-io">nums = [3]</span></p>

<p><strong>Output:</strong> 9</p>
</div>
