Binary numbers divisible by 3

WebSep 30, 2015 · Every term on the right other than the sum of the digits is divisible by $3$. So the remainder when dividing the original number by $3$ and the sum of the digits by $3$ must be the same. Share. Cite. Follow edited Oct 5, 2015 at 18:48. Alexander Belopolsky. 649 4 4 ... WebSince your input is binary, you can easily work in base b = 2 m. If n = ∑ i = 0 r d i b i, clearly n ≡ ∑ i = 0 r d i ( mod p k), and p k ∣ n iff p k ∑ i = 0 r d i. In other words, you’re in a position to use an analogue of the familiar sum-of-the-digits test for divisibility by 3 or 9 in ordinary decimal notation.
