Hi everybody.  
I am sorry if this is the inappropriate category, but I’m new to the forum (and to Julia) and I did not find any other fitting category.  
I was looking for the simple least common multiple function “lcm()” to understand if it takes more arguments than two, which is what it actually does, i.e. it returns 12 if I write lcm(2,3,4). Anyway, there is no “description” in the “help” environment about it, it just mentions the possibility to write two input arguments lcm(x,y). Also, in the page [Mathematics · The Julia Language](https://docs.julialang.org/en/v1/base/math/#Base.lcm) it does the same.

Should these descriptions be updated?

Thanks!

I’ve opened a PR for this here: [https://github.com/JuliaLang/julia/pull/37911](https://github.com/JuliaLang/julia/pull/37911)

Edit: and welcome!
