    Given the total number of user interactions on a viral social media post, calculate the sum of all possible audience segment sizes that could have contributed equally to the total engagement, where each segment size must divide perfectly into the total interaction count. This value will be used to optimize content distribution strategies and identify ideal audience targeting segments for similar content in the future.
