The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.
9 because the digits of 36 add up to 9
There is no easy rule for divisibility by 34.
why does the divisibility rule work for 4
By tautology. If it did not work, it would not be a divisibility rule!
there is a divisibility for 24 the rule is you can divide 24 as 6 and 4 i think
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
What is the divisblity rule by 8
The divisibility rule for 2 works because the base of our number system, 10, is divisible by 2.
There is no rule for 7 :P
Judging by some of the questions asked on this site, the first rule is that divisibility is a concept that applies only to whole numbers.
2 squared 1 = 4 so the divisibility rule is that it is divisible by 1, 2 and 4.
By using the divisibility rule for 3, we find that 117 is divisible by 3. That makes it composite.
Able to Be Divided
There is no divisibility rule for 13 because it is a prime number. If you are thinking: why is there a divsibility rule for 2 and 3 then. Well, i don't know so go look it up on google.
The rule for 1 and the rule for 3.
the number is even.
It has to end 00.
It is 86
it is divisible by5
Use the divisibility rule for 10. If the number is divisible by 10, then it is obviously also divisible by 5.
it is divisible by 3 and 9
Division by zero is undefined.
