%0 Journal Article %T The lcm(1,2,...,n) as a product of sine values sampled over the points in Farey sequences %A Peter Luschny %A Stefan Wehmeier %J Mathematics %D 2009 %I arXiv %X Recently Greg Martin derived an interesting formula for the least common multiple of {1,2,...,n}. Here, we give an exposition of a concise proof in terms of the sine function. %U http://arxiv.org/abs/0909.1838v1
