minus-square@logicbomblink8•1 year agoI looked up a rule for 7, and it seems like it would take about the same amount of time as actually dividing the number by 7. Meanwhile, it looks like the rule for 8 is to see if the last 3 digits are divisible by 8, which seems like a real time save for big numbers.
