There is no easy rule for divisibility by 34.
The special divisibility rule of 17 is "Take the difference of the rest of the digits and the last digit times 5." For instance: 17 1 - 7 * 5 = 1 - 35 = -34 which is divisible by 17.
By tautology. If it did not work, it would not be a divisibility rule!

The rule is: if a number is divisible by 5 and 17 at the same time, that number is divisible by 85

The divisibility rule for 2 works because the base of our number system, 10, is divisible by 2.

Judging by some of the questions asked on this site, the first rule is that divisibility is a concept that applies only to whole numbers.
2 squared 1 = 4 so the divisibility rule is that it is divisible by 1, 2 and 4.
the number is even.
There is no divisibility rule for 13 because it is a prime number. If you are thinking: why is there a divsibility rule for 2 and 3 then. Well, i don't know so go look it up on google.
