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.

117 is a composite. I know because suming the digits is 9. A number is a multiple of 117 if it's a multiple of 9 and 13 at the same time
Just carry out the division.
It is 3 6 9

The number must be divisible by 13 and by 11.
13 is a prime number - it can only be divided by 1 and itself (for an integer answer).
By tautology. If it did not work, it would not be a divisibility rule!
What is the divisblity rule by 8
There is no easy rule for divisibility by 34.
The divisibility rule for 2 works because the base of our number system, 10, is divisible by 2.

A number is a multiple of 741 if it's a multiple of 3, 13 and 19 at the same time 741 = 3 x 13 x 19
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.
Subtract nine times the last digit from the rest; repeat if necessary. The result must be divisible by 13.
