This one works best for very large number and it is one that I came up with myself. If you can split the number in half THREE times and the number is still even- it is a multiple of 16. Example- 32 32÷2=16 that's one 16÷2=8 that's two. 8÷2=4 that's the third time and it's still even! That means 32 is multiple of 16. Please note-The number ALWAYS has to start out even to be a multiple of any even number, that is because fractions can go till infinity, just like the largest number in the world.
The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.
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

In order for a number to be divisible by 16, the last four digits of the number must form a multiple of 16.
By using the divisibility rule for 3, we find that 117 is divisible by 3. That makes it composite.
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
