Sorry about the english its because im portuguese
Not really. The principle is the same but whereas with the Lowest Common Multiple you simply start to divide by 2 (or 3) and stop when you find a match, with the Highest Common Multiple after starting by dividing by 2 (or 3) you then work with the result of dividing by 2 (or 3).

Please don't apologise for language problems. Your English is better than my French or German and I know nothing about any other language

Please tell me if you need any other help.
