Best Answer

To be divisible by 9, sum the digits of the number and if this sum is divisible by 9, then the original number is divisible by 9.

As the test can be repeated on the sum, repeat the summing until a single digit remains; only if this number is 9 is the original number divisible by 9.

For 516 this gives:

→ 5 + 1 + 6 = 12

→ 1 + 2 = 3

3 is not 9 so 516 is not divisible by 9.

(This single digit is known as the digital root of the number.)

Any of its factors

Yes. 516 is indeed divisible by the number 3. The answer would be 172, since 172 goes into 516 precisely 3 times. You can check this by multiplying 3 x 172 to see for yourself.

The numbers that are divisible by 172 are infinite. The first four are: 172, 344, 516, 688 . . .

NO. 1110 is not divisible by 9. A number is divisible by 9 if the sum of its digits is divisible by 9. 1110 = 1 + 1 + 1 + 0 = 3 (3 is not divisible by 9, thus, 1110 is not divisible by 9.)

No it is not divisible by 9 .

NO. 1110 is not divisible by 9. A number is divisible by 9 if the sum of its digits is divisible by 9. 1110 = 1 + 1 + 1 + 0 = 3 (3 is not divisible by 9, thus, 1110 is not divisible by 9.)

81: 8 + 1 = 9 which is divisible by 9, so 81 is divisible by 9 162: 1 + 6 + 2 = 9 which is divisible by 9, so 162 is divisible by 9 199: 1 + 9 + 9 = 19 → 1 + 9 = 10 → 1 + 0 = 1 which is not divisible by 9, so 199 is not divisible by 9. 1125: 1 + 1 + 2 + 5 = 9 which is divisible by 9, so 1125 is divisible by 9. So 199 is the only one not divisible by 9.

All numbers divisible by 3 are NOT divisible by 9. As an example, 6, which is divisible by 3, is not divisible by 9. However, all numbers divisible by 9 are also divisible by 3 because 9 is divisible by 3.

No it is not divisible by 9 .

No - any number divisible by 9 will have the sum of its digits divisible by 9.
