There are two parts to the rule:
Part 1:
If the last but one digit is even, the last digit must be 0, 4 or 8
If the last but one digit is odd, then the last digit must be 2 or 6.
Part 2:
Find the sum of the first, third, fifth, etc digits.
Find the sum of the second, fourth, sixth, etc digits.
The difference between these two sums must be a multiple of 11 ie 0, 11, 22, 33 etc.
Part 1 ensures divisibility by 4
Part 2 ensures divisibility by 11
Together, they ensure divisibility by 44.
There is no easy rule for divisibility by 34.
By tautology. If it did not work, it would not be a divisibility rule!
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.
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!
why does the divisibility rule work for 4
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 a divisibility for 24 the rule is you can divide 24 as 6 and 4 i think

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.
