This one works best for very large number and it is one that I came up with myself. If you can split the number in half THREE times and the number is still even- it is a multiple of 16. Example- 32 32÷2=16 that's one 16÷2=8 that's two. 8÷2=4 that's the third time and it's still even! That means 32 is multiple of 16. Please note-The number ALWAYS has to start out even to be a multiple of any even number, that is because fractions can go till infinity, just like the largest number in the world.

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.
Just carry out the division.
It is 3 6 9

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.

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.

Division by zero is undefined.
