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 13156 divisble by?
To determine the divisibility of 13156, we can check for divisibility by common factors. It is divisible by 2 since it is an even number. Additionally, it can be divided by 4 (as the last two digits, 56, form a number divisible by 4) and by 13 (since 13156 ÷ 13 = 1012). Other factors can be found through further factorization.
