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.
Life with the GMAT:
Jerome: Ben, c'est 20 secondes de plus qu'hier sur le meme parcours! C'etait bien le meme parcours la, non?!
Gigi: Mais t'enerve pas, Jerome, je crois que t'as accroche une porte.
