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.

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 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.

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

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.

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.

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

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

Yes, because 12 is divisible by 2 and 6.

Numbers that are divisible by 2 through the number 12 are: 4, 6, 8, 10 and 12.

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

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.

You can tell a number is divisible by 3 when the sum of its digits is equal to 3 or a multiple of three. In this instance, 1 + 2 + 9 = 12/3 = 4, therefore 129 is divisible by 3.

Not always because 18 is divisible by 2 and 6 but not by 12

Multiples of 12 are even. Start with 999998. It's not divisible by 12. Try 999996. It is divisible by 12. Stop there.

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

If it's even and divisible by 3, it's divisible by 6.

a number is divisible by 12 if the number is also divisible by both 3 and 7. You mean a number is divisible by 21 if it is divisible by 3 and 7.

Nope, 10 is divisible by 5, 2, and 1. You are looking for the number 12. 12 is divisible by 6.

Not always because 30 is divisible by 2 and 6 but not by 12

if the last digit is even or 0, a number is divisible by 2!

Yes. 1 + 2 + 9 = 12 12 is divisible by 3. If the sum of the digits of a number are divisible by 3, then the whole number is divisible by 3. 129 is a composite number because it divisible by a factor other than 1 and itself.

Yes.
