Least common multiple


The least common multiple of some integers is usually written as \([a,b,...]\) or \(lcm(a,b,...)\), which means the smallest positive number that can divisible by \(a,b,...\)

for example:


(sorry for my bad English...) 


\(lcm(1,2,3,...,42)\) = ?

\(lcm(1,2,3,...,42)\) = ?
