- 22/02/2002 · It talks about how you can tell whether a number is divisible by 9. The idea is that if you have digits a,b in some number, with place value the "a" is "worth" a * 10^n and b is worth b * 10^(n-1). So in total the ab is worth a * 10^n + b * 10^(n-1), or 10^(n-1) * (10a + b) When you switch them, the "ba" is then worth 10^(n-1) * (10b+a). So the difference is 10^(n-1) * (9a - 9b), which is sure
- Numbers are divisible by 8 if the number formed by the last three individual digits is evenly divisible by 8. For example, the last three digits of the number 3624 is 624, which is evenly divisible by 8 so 3624 is evenly divisible by 8.
- I know that doing, i.e, 130 % 13 will result into doing 130 / 13 per 10 times. So there are 10 cycles when just one is needed (I just want to know if 130 is divisible by 13). So there are 10 cycles when just one is needed (I just want to know if 130 is divisible by 13).
