%0 Journal Article %T An analog of the arithmetic triangle obtained by replacing the products by the least common multiples %A Bakir Farhi %J Mathematics %D 2010 %I arXiv %X In this paper, we introduce an analog of the Al-Karaji arithmetic triangle by substituting in the formula of the binomial coefficients the products by the least common multiples. Then, we give some properties and some open questions related to the obtained triangle. %U http://arxiv.org/abs/1002.1383v2
