The IOS Least Common Multiple (LCM) App was created in response to requests by visitors to the popular https://multiples.info website. This app will not only find the LCM of your numbers, but it will also calculate the multiplier you need to multiply each number by to get the LCM. The app is fast, intuitive, and easy to use. 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.
