<p>You are given an integer array of unique positive integers <code>nums</code>. Consider the following graph:</p>
|
|
|
|
<ul>
|
|
<li>There are <code>nums.length</code> nodes, labeled <code>nums[0]</code> to <code>nums[nums.length - 1]</code>,</li>
|
|
<li>There is an undirected edge between <code>nums[i]</code> and <code>nums[j]</code> if <code>nums[i]</code> and <code>nums[j]</code> share a common factor greater than <code>1</code>.</li>
|
|
</ul>
|
|
|
|
<p>Return <em>the size of the largest connected component in the graph</em>.</p>
|
|
|
|
<p> </p>
