WebMay 1, 2016 · Adding a 0 to the end of a binary number has the effect of multiplying it by 2. Adding a 1 multiplies it by 2, then adds 1. For a number x to be divisible by 5, x % 5 = 0 (where % is the modulus operator). Consider what (x * 2) % 5 and (x * 2 + 1) % 5 would look like for the five cases x % 5 = 0, x % 5 = 1 … x % 5 = 4. WebNov 2, 2011 · I know this is an old question, but an efficient answer is yet to be given and this question pops up first for "binary divisible by 3 regex" on Google. Based on the DFA proposed by the author, a ridiculously short regex can be generated by simplifying the routes a binary string can take through the DFA. The simplest one, using only state A, is: 0*
