In terms of the character set used by most non-European countries there is no difference. Some European countries use a comma as a decimal indicator and the full stop as a thousands separator. For example, UK/US 1,234.56 would be written as 1.234,56 It is simply a case of using common punctuation symbols to indicate key positions in a number. That is one reason that, if the last part of my sentence on this site is a number, I frequently do not end with a full stop.
The smallest 3 digit number full stop is 100, as every smaller number has 2 digits. 100 divides by 4, thus the answer is 100.
