Why do even numbers have more factors than odd numbers?

Even numbers have more factors than odd numbers primarily because they include 2 as a factor, which allows for additional combinations. Since even numbers can be divided by 2, they can be paired with other factors, leading to a greater total number of divisors. In contrast, odd numbers only consist of odd factors, which often limits their combinations and results in fewer total factors. Consequently, even numbers tend to have a richer structure in terms of divisibility.
