<p>给定一个由不同正整数的组成的非空数组&nbsp;<code>nums</code> ，考虑下面的图：</p>

<ul>
	<li>有&nbsp;<code>nums.length</code>&nbsp;个节点，按从&nbsp;<code>nums[0]</code>&nbsp;到&nbsp;<code>nums[nums.length - 1]</code>&nbsp;标记；</li>
	<li>只有当&nbsp;<code>nums[i]</code>&nbsp;和&nbsp;<code>nums[j]</code>&nbsp;共用一个大于 1 的公因数时，<code>nums[i]</code>&nbsp;和&nbsp;<code>nums[j]</code>之间才有一条边。</li>
</ul>

<p>返回 <em>图中最大连通组件的大小</em> 。</p>
