Let's discuss Mathematics

I assume it's a typo ? Technically the answer is actually -1 because the question doesn't state it's the lowest common positive factor, but that's even more ridiculous.

Now wouldn't it be really something if this was a test question and indeed they wanted -1? ^^

Does that mean that technically the lowest common multiple of any two numbers is minus infinity (or aleph null or whatever)?

 

[AdrienIer]

The common definition of "lowest common multiple" states that it's the lowest common positive multiple, but if you don't take that part into account I would say there is no lowest common multiple. You define a multiple of A as a number B where there exists another integer K for which A times K = B. Therefore minus infinity is not a multiple of whatever number you chose.

See what a difference non-vertex smaller dot markers make? ^^
