The IOS Least Common Multiple (LCM) App was created in response to requests by visitors to the popular https://multiples.info website.

It is a standalone app, which means that it will work perfectly fine in places with little or no Internet access. We hope the Least Common Multiple App will become one of your favorite math apps.
