Rules: 2: the number has to be even, ex: 46 & 82 3: add each digit, if it is divisible by 3, ex: 39, 3 + 9 = 12, which is divisible by 3, so 39 is divisible by three 4: if the number can be divided by 2 two times, 48 divided by 2 = 24 divided by 2 is 12. So 48 is divisible by 4 5: the last digit must be 0 or 5, ex: 45 and 120 6: the number should be even and divisible by 3, ex: 66, 66 is even and 6 + 6 can be divided by 3. so 66 is divisible by 6 9: add each digit, if it is divisible by 9. 189 = 1 + 8 + 9 = 18 can be divided by 9 so 189 is divisible by 9 10: the last digit must be 0, ex: 40 and 5600
