Tue, 07 Feb 2012 01:47:49 +0000https://blog.tanyakhovanova.com/?p=309#comment-1812so i tested the question “Suppose that n is the product of three consecutive integers and that n is divisible by 7. Which of the following is not necessarily a divisor of n?” with choices 6, 14, 21, 28, 42. when i used the three consecutive numbers 7,8,9, multiplied together it was 504. that integer was divisible by all the choices 6, 14, 21, 28, 42. so im just wondering if i was forgetting any information given by the question, it would be very nice to find out where if at all i messed up.

other than that great website, helps a lot
