If the last three digits of the number are divisible by 8, then the whole number is divisible by 8. example= 24,960 is divisible by 8, because 960 (the last three numbers) is. 258,460 is not, because you cannot evenly divide 460 by 8. Works great for big numbers!
Well that's a great one, but I have one that works better and it's quicker to find- split the number in half twice, if it is possible (still even) it is divisible by eight.
why does the divisibility rule work for 4
What is the divisblity rule by 8
there is a divisibility for 24 the rule is you can divide 24 as 6 and 4 i think
There is no easy rule for divisibility by 34.
By tautology. If it did not work, it would not be a divisibility rule!

The number formed by the last three digits have to be divisible by 8.
There is no easy rule for divisibility by 34.
The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.
By tautology. If it did not work, it would not be a divisibility rule!
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
That the last digit is 0. 2 4, 6 or 8.
The divisibility rule for 22 is that the number is divisible by 2 and by 11. Divisibility by 2 requires that the number ends in 0, 2, 4, 6 or 8. Divisibility by 11 requires that the difference between the sum of the the digits in odd positions and the sum of all the digits in even positions is 0 or divisible by 11.
A divisibility rule is a statement of procedures to determine divisibility. For example:"A number is divisible by 2 if it ends with 0, 2, 4, 6 or 8".It does not make any sense to divide such a sentence by 2 or 895 or any other number!
A number is divisible by 8 if and only if it is an integer and the last three digits make a number that is divisible by 8. A general divisibility rule for 2^n where n is an integer is to take the last n digits and if they make a number that is divisible by n then it is divisible by n.
