There is no simple rule for finding out if a number if divisible by 13.
The only method that I know is as follows:
- Split the number into two parts: the first part (A) comprises all but the last (units) digit, and the second part B is the units digit.
- Calculate A+4B
- Repeat with this new number until you reach 13, 26 or 39 (or 0 if you are looking for divisibility of 0!). Any
So, for example,
1755 gives 175 + 4*5 = 175 + 20 = 195
195 gives 19 + 4*5 = 19 + 20 = 39
therefore 1755 is divisible by 13.

What is the divisibility rule for 13?
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.
What is the divisibility for 91?
All Factors of 91:1, 7, 13, 91
What divisibility rules were combined to make the divisibility rule of 36?
The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.
What are the divisibility rules for 1 through 50?
Do the division, if there is no remainder, it is divisible. Seriously, many of the "divisibility rules" that have been discovered become more complicated than doing the actual division. For practical purposes, just learn the divisibility rules for a few simple cases (divisibility rules by 2, 4, 8, 5, 10, 3, 9, 7, 11, and 13), and for all other cases, just do the division.
What are the divisablity rules?
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

Does 39 divide the product of 3 X 5 X 7 X 11 and if not what is the smallest missing factor that would allow for divisibility of the product?
no it does not and the smallest missing factor that would allow for divisibility is 13

It is somebody talking about divisibility.
What is the divisibility rule for thirteen?
Subtract nine times the last digit from the rest; repeat if necessary. The result must be divisible by 13.
Why does divisibility rule for 6 work?
By tautology. If it did not work, it would not be a divisibility rule!
