Some number that u don't know

For that you just need to know the trick which helps you find out by which number is the given number divisible. 
like suppose you're given the no. 27
you would think of 3 and thats right you can also find it if you dont know, just add the two digits 2+7=9 since 9 is divisible by 3 so 27 is divisible by 3.
in a similar way all the nos. except 7 has got a way to find divisibility
