<p>You are given an array of integers <code>nums</code>. Perform the following steps:</p> <ol> <li>Find <strong>any</strong> two <strong>adjacent</strong> numbers in <code>nums</code> that are <strong>non-coprime</strong>.</li> <li>If no such numbers are found, <strong>stop</strong> the process.</li> <li>Otherwise, delete the two numbers and <strong>replace</strong> them with their <strong>LCM (Least Common Multiple)</strong>.</li> <li><strong>Repeat</strong> this process as long as you keep finding two adjacent non-coprime numbers.</li> </ol> <p>Return <em>the <strong>final</strong> modified array.</em> It can be shown that replacing adjacent non-coprime numbers in <strong>any</strong> arbitrary order will lead to the same result.</p> <p>The test cases are generated such that the values in the final array are <strong>less than or equal</strong> to <code>10<sup>8</sup></code>.</p> <p>Two values <code>x</code> and <code>y</code> are <strong>non-coprime</strong> if <code>GCD(x, y) > 1</code> where <code>GCD(x, y)</code> is the <strong>Greatest Common Divisor</strong> of <code>x</code> and <code>y</code>.</p> <p> </p> <p><strong>Example 1:</strong></p> <pre> <strong>Input:</strong> nums = [6,4,3,2,7,6,2] <strong>Output:</strong> [12,7,6] <strong>Explanation:</strong> - (6, 4) are non-coprime with LCM(6, 4) = 12. Now, nums = [<strong><u>12</u></strong>,3,2,7,6,2]. - (12, 3) are non-coprime with LCM(12, 3) = 12. Now, nums = [<strong><u>12</u></strong>,2,7,6,2]. - (12, 2) are non-coprime with LCM(12, 2) = 12. Now, nums = [<strong><u>12</u></strong>,7,6,2]. - (6, 2) are non-coprime with LCM(6, 2) = 6. Now, nums = [12,7,<u><strong>6</strong></u>]. There are no more adjacent non-coprime numbers in nums. Thus, the final modified array is [12,7,6]. Note that there are other ways to obtain the same resultant array. </pre> <p><strong>Example 2:</strong></p> <pre> <strong>Input:</strong> nums = [2,2,1,1,3,3,3] <strong>Output:</strong> [2,1,1,3] <strong>Explanation:</strong> - (3, 3) are non-coprime with LCM(3, 3) = 3. Now, nums = [2,2,1,1,<u><strong>3</strong></u>,3]. - (3, 3) are non-coprime with LCM(3, 3) = 3. Now, nums = [2,2,1,1,<u><strong>3</strong></u>]. - (2, 2) are non-coprime with LCM(2, 2) = 2. Now, nums = [<u><strong>2</strong></u>,1,1,3]. There are no more adjacent non-coprime numbers in nums. Thus, the final modified array is [2,1,1,3]. Note that there are other ways to obtain the same resultant array. </pre> <p> </p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= nums.length <= 10<sup>5</sup></code></li> <li><code>1 <= nums[i] <= 10<sup>5</sup></code></li> <li>The test cases are generated such that the values in the final array are <strong>less than or equal</strong> to <code>10<sup>8</sup></code>.</li> </ul>
