Divisibility Rules

Divisible By Description
2 if the last digit of Number is even (2, 4, 6, 8 or 0)
3 if the sum of digits of Number is divisible by 3
4 if the last 2 digits of Number is divisible by 4
5 if the last digit of Number is either 0 or 5
6 if the number is divisible by both 2 and 3
7 subtract twice the last digit of Number from the remaining digits. If the result is result is divisible by of 7 , the number is divisible by 7 (Example 1022 is divisible by 7 because 102 - 2 x 2 = 98, which is divisible by 7)
8 if the last 3 digits of Number is divisible by 8
9 if the sum of digits of Number is divisible by 9
10 if the last digit of Number zero (0)
11 if the difference of the alternating sum of digits of the number is a multiple of 11 (e.g. 1331 is divisible by 11 because 1 - 3 + 3 - 1 = 0, which is a multiple of 11)
