Web23 de jul. de 2012 · 2. Write the original number as 10x+y to separate out the last digit ( y) from the number without the last digit ( x ). Recognize that divisibility by a 17 means you can write the number as 17n for a positive integer n. So our statement is if x-5y=17n then 10x + y = 17m, where x,y,m,n are positive integers. WebFast tests for divisibility depend heavily on the base in which the number is represented. In case when base is 2, I think you can only do "fast tests" for divisibility by powers of 2. A binary number is divisible by 2 n iff the last n binary digits of that number are 0. For other tests I don't think you can generally find anything faster than %.
