No remainder. It has the same rule as 3 for divisibility. Add them up and if that is divisible by 27 then the number is divisible by 27.
There is no easy rule for divisibility by 34.
The number must be divisible by 13 and by 11.
By tautology. If it did not work, it would not be a divisibility rule!
The divisibility rule for 22 is that the number is divisible by 2 and by 11. Divisibility by 2 requires that the number ends in 0, 2, 4, 6 or 8. Divisibility by 11 requires that the difference between the sum of the the digits in odd positions and the sum of all the digits in even positions is 0 or divisible by 11.

the number is even.
The divisibility rule for 2 works because the base of our number system, 10, is divisible by 2.
There is no easy rule for divisibility by 34.
If the number is even, it's divisible by 2.
The rule is: if a number is divisible by 5 and 17 at the same time, that number is divisible by 85
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.
