This tool finds numbers with a high number of divisors. Having a lot of divisors is a property that makes them a great choice as the number of partitions to use for sharding.
It also has the concept of "usable divisors", those that provide an increase greater or equal to some % (20% by default). Rebalancing has some operational costs and risks, so you usually wouldn't want to rebalance to achieve less

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.
Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.
