Is 51 87 2007 56789 6321 divisibal by 3?

Answer 1

Anyone who takes the trouble to ask this would get a quicker answer by trying it for themselves. You can divide it by 3, but you will have a remainder. For some people that means you can't divide it by 3. but in principle, any number can be divided by 3, for example 10/3 is three and one third. Harder to represent in the decimal system, but in base 9 instead of base 10, the answer is 3.
