There are specific rules to remember divisibility by numbers up to 10.

1: All numbers
2: Even numbers
3: Sum of digits = 3
4: Divisible by 2 twice/Last two digits divisible by 4
5: Last digit = 5 or 0
6: Divisible by 3 and 2
7: No divisibility rule
8: Divisible by 2 thrice/last three digits divisible by 8
9: Sum of digits = 9
10: Last digit = 0

Now for bigger numbers, what you basically need to do is assume they are divisible and check for consistency with constrains given in the problem.

For example if a question asks if a number x is divisible by 12 and gives you additional constraints say:

x = 12a

And then check against restrictions. But I'd say that beyond this the method would be case specific. Hope this helps!
