Take the last digit of the number Double and subtract it from the rest
the digits (Repeat the process for larger numbers.) if the difference
divisible by 7. then the number is divisible by 7
Example 1: 357 -- Double the 7 to 14. Subtract 14 from 35 to
which is divisible by 7. Hence, 357 is divisible by 7
Example 2: 3934 - Double 4 to get 8.393 - 8 = 385. Double 5 to
38 - 10 = 28.28 is divisible by 7. Hence, 3934 is divisible by 7
A number is divisible by 8 if the number formed by its last three digits
divisible by 8
