Divide the number by thirteen. If the answer comes out even with no remainder, the number is divisible by thirteen.

If a number is divisible by three you will know if all the digits of a number add up to a number divisible by three. Example: 1542 is your number, to find out if it is divisible by three you must add up the digits. 1+5+4+2=12. The number 12 is divisible by three(4x3) so therefore 1542 is divisible by three.

All multiples of 12, which is an infinite number.

If a number is divisible by both three and four, it's divisible by twelve.

To work this out, first write down the greatest 4 digit number 9999 then divide this by 12 9999/12 = 833.25 Take the number before the decimal point (833) and multiply this by 12 833*12 = 9996 9996 is the greatest four digit number that is divisible by 12.

A number is divisible by 4 if the last two digits form a number that is divisible by 4, for example 612 is divisible by 4 (because 12 is divisible by 4).

A number is divisible by 4 if the last two digits form a number that is divisible by 4, e.g. 312 is divisible by 4 (because 12 is divisible by 4).

If the sum of the digits can be divided by 3. 93 is divisible by 3 because 9+3=12 we know 12 is divisible by 3 because 1+2=3 so the number is divisible by 3.

Absolutely - any number that is divisible by 12 - is also divisible by 6 !

If the last two digits of a number are divisible by four, the whole number is divisible by four. This is related to the fact that 100 is a multiple of 4.For example, 12885212 is divisible by 4, because 12 is divisible by 4. No need to divide the entire number.

You can add up the digits, 6+4+2=12 and if that number is divisible by three, so it the original number. So 12 is certainly divisible by 3 so that means 642 is also.

If it ends with an even number then it is divisible by 2

A number is divisible by 12 if it is divisible by 3 AND it is divisible by 4. Rule 1a (Divisibility by 3): Add up all the digits of the number. Is this number divisible by 3? Rule 1b (Divisibility by 4): Is the number formed by the last two digits of the original number (the number left after deleting the hundreds, thousands, millions etc) divisible by 4? If the answer to 1a is NO, then the number is not divisible by 3 and so not divisible by 12. In this case, obviously, rule 1b is irrelevant. If the answer to 1b is NO, then the number is not divisible by 4 and so not divisible by 12. If the answer to both 1a and 1b is YES, then the number is divisible by 12.

No. 12 cannot be divisible by any number bigger than 12.

6, 9, 12, 30, 60, 90, 360, 690, 930, or (162,591). Here's a secret: If the sum of a number's digits is divisible by 3, then the number is divisible by 3. That's how you can tell quickly that 162,591 is divisible by 3.

Yes, because 12 is divisible by 2 and 6.

To be divisible by 3 and 4 the number must be divisible by 12. 201/12 = 16.75 so the smallest number in the range, divisible by 12, is 17*12 = 204 301/12 = 25.08 so the largest number in the range, divisible by 12, is 25*12 = 300 The number of multiples of 12 is 25 - 16 = 9
