3 Answers. Firstly, we know that any number of the combination of digits 1,2,3,7,8,9 with each number used exactly once is not divisible by 9, since 1+2+3+7+8+9=30 which is not divisible by 9. Secondly, to let the number be divisible by 6, the last digit must be even. Therefore the last digit can only be 2 or 8.

Which is an example of a number not divisible by 5?
Since the last digit is 0, this number is divisible by 5. Since the last digit is 5, this number is divisible by 5. Since the last digit is 5, this number is divisible by 5. Examples of numbers that are not divisible by 5 . To be divisible by 5, the last digit must be 0 or 5. So 11 fails this test.
Why are the last two digits of 11 not divisible by 4?
Since the last two digits, 13, are not divisible by 4, the whole number does not pass this divisibility test. The last two digits, 41, are not de visible by 4. Therefore, the whole number does not satisfy the rule for 4. Those last two digits, 14, do not work. 11 is not divisible by 4, so 1,011 fails this test. Ever wonder why these rules work.
When does a number pass the divisibility test?
In other words, a number passes this divisibility test only if it passes the test for 2 and the for 3 . Rule: A number is divisible by 6 if it is even and if the sum of its digits is divisible by 3. Examples of numbers that are divisible by 6. 1) 114 is even . 2) the sum of its digits (1 + 1 + 4 = 6) is divisible by 3.
