General question about consecutive numbers [#permalink] New post 05 Jul 2011, 00:55
I'm looking at page 53 of the MGMAT Number Properties guide and I have a question about "products of consecutive integers and divisibility".

It says that any 3 (or x) consecutive integers will always be divisible by 3 (or x). However, doesn't this only apply to non-zero numbers? For instance, -1, 0, 1 are consecutive integers but their product is clearly 0. The rest of the section in the chapter doesn't really clarify whether this rule (i.e. "the product of K consecutive integers is always divisible by k factorial") only applies to non-zero integers.

Someone help?

0 is divisible by 3.

0/3 = 0 (which is an integer)

Ahhhhhhhhhhhhhhh thank you so much!!! I thought 0 wasn't divisible because the result would be undefined but it's the other way around.
