What defines an abundant number and how does this tool identify them?

An abundant number is an integer greater than the sum of its proper divisors; the tool calculates the divisor sum for each integer and flags those where the sum exceeds the original number.

Can I generate abundant numbers starting from any positive integer?

Yes, you can input any starting number or range, and the tool will output abundant numbers within that specified span.

Is there a limit to how many abundant numbers the tool can generate at once?

The tool processes inputs within the range you provide; very large ranges may take longer to compute, but there is no stated hard limit on output quantity.

Do the generated abundant numbers include the starting number if it is abundant?

The tool outputs abundant numbers within the input range; whether the starting number itself appears depends on whether it meets the abundant number criteria.
