Is 896 divisible by 2 3 5 9 or 10?
896 is only divisible by 2; it is not divisible by 3, 5, 9 nor 10. To be divisible by 2, the number must be even, ie, the last digit must be even, that is one of {0, 2, 4, 6, 8}; 896 ends in 6 which is even, thus 896 is divisible by 2. To be divisible by 3, add the digits of the number together and if the sum is divisible by 3, then so is the original number. The test can be repeated on the sum until a single digit remains; if this single digit is 3, 6, or 9 then the original number is divisible by 3: 896 → 8 + 9 + 6 = 23 → 2 + 3 = 5 which is not one of {3, 6, 9}, thus 896 is not divisible by 3 To be divisible by 5, the last digit must be 0 or 5; 896 ends in 6 which is neither 0 nor 5, so 896 is not divisible by 5. To be divisible by 9, add the digits of the number together and if the sum is divisible by 9, then so is the original number. The test can be repeated on the sum until a single digit remains (which is called the digital root of the number); only if this single digit is 9 will the original number be divisible by 9: 896 → 8 + 9 + 6 = 23 → 2 + 3 = 5 which is not one 9 thus 896 is not divisible by 9; To be divisible by 10 the last digit must be 0; 896 ends if 6 which is not 0, so 896 is not divisible by 10.

What number is not divisible 7?
23 is not divisible by 7.
Is 21 divisible by 2 3 or 5?
21 is not divisible by 2 nor 5, but it is divisible by 3. To be divisible by 2 the last digit must be even (one of {0, 2, 4, 6, 8}; the last digit 1 is not one of these, thus 21 is not divisible by 2 To be divisible by 3 sum the digits and if this total is divisible by 3, then so is the original number; the test can be repeated on the sum, so by repeatedly summing the digits of the totals until a single digit remains only if that single digit is 3, 6 or 9 is the original number divisible by 3. 21 → 2 + 1 = 3 which is divisible by 3 so 21 is divisible by 3. To be divisible by 5, the last digit must be 0 or 5. The last digit of 21 is 1 which is not 0 nor 5, thus 21 is not divisible by 5.
What is 8487 divisibility rule?
The number must be divisible by 9, 23 and 41, so all three of the following conditions must be met.Divisibility by 9 requires you to check the sum of the digits is divisible by 9.Divisibility by 23 requires you to add 7 times the last digit to the rest. The answer must be divisible by 23 directly.For divisibility by 41, subtract 4 times the last digit from the rest. The answer must be divisible by 23 directly.In each case, the additions or subtractions can be repeated so as to make the answer easier to test for divisibility.
