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.

That the number is divisible by 4* and the sum of its digits is a multiple of 3. *If the number has three of more digits then it is only necessary to look at the tens and units to determine if it is divisible by 4, as 4 is a factor of 100 and therefore of any multiple of 100. Examples : 75 : is not divisible by 4 although its digits total 12 which is a multiple of 3. 132 : is divisible by 4 as 32 is divisible by 4, and its digits total 6 which is divisible by 3, then 132 is divisible by 12.
