6
No. There is no whole number you can multiply 6 by to get 3 (3/6 is 1/2 which isn't a whole number).
If the sum of the digits is a multiple of three, the whole number is a multiple of three.
No, 28 could not be a multiple of 3.No. 28 divided by three is not a whole number, so it is not a multiple of three.
Because when you divide 3 into 103 the answer is not a whole number.
Three is not a multiple of 6 because you can't multiply 6 by a whole number and get the answer 3.
If the digits of the number add up to a multiple of 3, the whole number is divisible by 3.
Divide it by 3, and if its a whole number with no .'s then it's a multiple of 3. 3x=3269283 x=1089761 3269283 is a multiple of 3
Do the division, 617 / 3. If you get a whole number, it's a multiple; otherwise it isn't.
If the number is even, it's divisible by 2. If the sum of the digits is a multiple of 3, the whole number is divisible by 3. If the last two digits are a multiple of 4, the whole number is divisible by 4. If the last digit is a 0 or a 5, the whole number is divisible by 5. If the number is even and divisible by 3, it's divisible by 6. If the last digit doubled subtracted from the rest is a multiple of 7, the whole number is divisible by 7. If the last three digits are a multiple of 8, the whole number is divisible by 8. If the sum of the digits is a multiple of 9, the whole number is divisible by 9. If the number ends in 0, it's divisible by 10.

If the number is even, it's divisible by 2. If the sum of the digits is a multiple of 3, the whole number is divisible by 3. If the last two digits are a multiple of 4, the whole number is divisible by 4. If the last digit is a 0 or a 5, the whole number is divisible by 5. If the number is even and divisible by 3, it's divisible by 6. If the sum of the digits is a multiple of 9, the whole number is divisible by 9. If the number ends in 0, it's divisible by 10.
It has to be a whole number, or else every number would be a multiple of every other number.
