GCD and LCM calculator - calculate the Greatest Common Factor/Greatest Common Divisor and the Least Common Multiple. The app finds the greatest common divisor (GCD)/greatest common factor (GCF) and Least Common Multiple (LCM) of two, three numbers and four numbers. Finds the prime factorization of numbers and shows it in the standard and exponential forms. Just enter two, three or four integers and tap "Calculate". The app lists all factors and identifies the common ones. Keeps calculation history. Sends results and history via email. Supports both portrait and landscape orientation.

『飛行機（plane）を左右に操作して倍数をキャッチしよう』 飛行機を左右にドラッグして操作し、倍数（雲）をキャッチしましょう 倍数をキャッチすると得点が増えます 大きな倍数ほど高得点になります 倍数でない数をキャッチするとミスになります ５回ミスするとゲームオーバーです 倍数を10個キャッチすると、風船アイテムが出現します 風船アイテムは５種類です 赤：ヒントアイテム：倍数がわかりやすくなるよ 橙：大きさアイテム：雲の大きさが同じになるよ 黄：速さアイテム：速度がゆっくり一定になるよ 緑：大量アイテム：倍数の数だけが出るようになるよ 青：無敵アイテム：ミスが０になって無敵になるよ 風船アイテムは風でゆらゆらするので、上手にキャッチしましょう

Verdict
The clearest difference is price: 倍数plane at Free against GCD and LCM's $3.99. 倍数plane also leads on update cadence (every 6 months vs every 19 months). GCD and LCM's advantage is iOS requirement (12.0 vs 15.0). On ads, in-app purchases and device support there is nothing between them.
