Comment on Divisibility Rules

Hi, are there any similar rules for 7? How do we determine if a large number is divisible by 7 and also by other prime numbers?

There are other rules for other numbers (like 7, 8, 11, etc), but I've never seen an official GMAT question that requires those rules. So, we have left them out.

Sure, thanks!
And thank you for this really wonderful video course!
