There is no simple rule for finding out if a number if divisible by 13.The only method that I know is as follows:Split the number into two parts: the first part (A) comprises all but the last (units) digit, and the second part B is the units digit.Calculate A+4BRepeat with this new number until you reach 13, 26 or 39 (or 0 if you are looking for divisibility of 0!). AnySo, for example,1755 gives 175 + 4*5 = 175 + 20 = 195195 gives 19 + 4*5 = 19 + 20 = 39therefore 1755 is divisible by 13.
