If a number is divisible by 3, and also by 4, then it is divisible by 12 - so you might use the divisibility rules for those two numbers. Although it might be simpler just to perform the division.
There is no easy rule for divisibility by 34.
it is divisible by5
it is divisible by 3 and 9
there is a divisibility for 24 the rule is you can divide 24 as 6 and 4 i think
The number must be divisible by 13 and by 11.
the divisibility rule for 2 is: The number is even;the last digit ends with a 2,4,6,8,10, etc.The divisibility rule fir 3 is: The sum of the number is divisible by 3The divisibility rule for 4 is: The last two digits are divisible by 4The divisibility rule for 5 is: The number ends with a 5 or 0The divisibility rule for 6 is: The sum CAN be divisible by 2 and or 3The divisibility rule for 9 is: The sum of the number is divisible by 9The divisibility rule for 10 is : The number ends with a 0
There is no easy rule for divisibility by 34.
129 is divisible by 3. 1+2+9=12 and 12 is divisible by 3. That is the rule of divisibility by 3.
it is divisible by5
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.
Use the divisibility rule for 10. If the number is divisible by 10, then it is obviously also divisible by 5.
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.
it is divisible by 3 and 9

The divisibility rule for 2 works because the base of our number system, 10, is divisible by 2.
The rule is: if a number is divisible by 5 and 17 at the same time, that number is divisible by 85
2 squared 1 = 4 so the divisibility rule is that it is divisible by 1, 2 and 4.
