Type in a number and watch it go! Note: Lists in Scratch have a limit of 200,000 items. So think twice before putting in extremely large numbers. Updates: 1.1: Calculation time is now highly optimized. (It stops when it reaches the square root of the input number.) 1.2: Factors are now listed in order of greatest to least. 1.3: There is now an option to search the list for certain factors.
