Parti1.0.0

Enter divisors into Parti to build a list and see their least common multiple (LCM) and greatest common divisor (GCD) recalculate as the list changes. The editor accepts one divisor at a time, while a control beside the input adds or removes it from the list.

Tap a listed value to return it to the editor. Drag it left to remove it and load it into the editor, or drag it right to remove it without changing the editor. Controls in the top bar clear the full list or undo and redo changes made during the current session.

Parti also lets you tap the displayed GCD and replace it with any whole number, set it to 1, restore its previous value, or increase or decrease it by one; the divisor list updates to match. Its calculations use BigInts, allowing whole-number values to grow within the device’s available memory. Designed for studying fraction-based parts with differing divisors, Parti runs on Android 4.4 or later with the arm64-v8a architecture.
