All numbers that are divisible by 8 and 12 would also be divisible by 4.
Are all even numbers which are divisible by 4 divisible by 8?
No. The reverse is true, but 12 is divisible by 4 and not by 8.
Is 1272 divisible by 4?
Yes. 1272 is divisible by 4. Total of the individual digits 1272 comes to 12 which is divisible by 4 and hence ....
What is the rule to determine if a 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.
Write a rule to determine when a number is divisible by 12?
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.
Can 612 divisible by 4?
612 is divisible by 4. To test divisibility by 4, if the last 2 digits of the number are divisible by 4, then the whole number is divisible by 4. Last 2 digits of 612 are 12, and 12 is divisible by 4 since 3x4 = 12, so 612 is divisible by 4. 612 / 4 = 153.

How can you tell if a number is divisible by 4?
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).
How do you tell at a glance that a number 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).
All numbers divisible by 8 and 12 are also divisible by?
All numbers that are divisible by 8 and 12 would also be divisible by 4.
