67,192,198,651,623's L.C.M.is???

用短除法
3 / (67,192,198,651,623)
7 / (67,64,66,217,623)
2 / (67,64,66,31,89)
8 / (67,32,33,31,89)
2 / (67,4,33,31,89)
11/ (67,2,33,31,89)
67,2,3,31,89
將左手邊果排數字乘以最底果排數就係嫁啦!!!所以
L.C.M.=3x7x2x8x2x11x67x2x3x31x89
=8198600256

我打唔到短除法個格式比你睇
希望你睇得明啦^^
個數太大,我唔知有冇計錯
希望可以幫到你啦!
