It really isn't worthwhile to find complicated divisibility rules for large numbers like 305 - because if there really is a divisibility rule, it will certainly be more complicated than just doing the division.
Anyway, 305 = 5 x 61, so if a number is divisible by 305, it must be divisible by 5, and by 61. Divisibility by 5 is fairly simple; a number is divisible by 5 if it ends with 0 or 5. For divisibility by 61, see the following link; it looks fairly complicated.

1 and 5.
Is 305 divisible by 2 3 5 6 9 10?
Well, honey, let's break it down. 305 is not divisible by 2, 3, 5, or 6 because it's an odd number and doesn't meet the divisibility rules for those numbers. As for 9 and 10, nope, it doesn't work for them either because the sum of the digits of 305 isn't divisible by 9, and it doesn't end in 0 for 10. So, in short, 305 is a lone wolf that can't be divided by any of those numbers.
