The divisibility rule of 7 states that for a number to be divisible by 7, the last digit of the given number should be multiplied by 2 and then subtracted with the rest of the number leaving the last digit. If the difference is 0 or a multiple of 7, then it is divisible by 7.

According to the divisibility rule of 8, if the last three digits of a given number are zeros or if the number formed by the last three digits is divisible by 8, then such a number is divisible by 8.
