Hello !!

For you answer this question correctly, you can use the method of prime factorization. See the resolution below.

$\begin{array}{r|l}6,8,45&2\\3,4,45&2\\3,2,45&2\\3,1,45&3\\1,1,15&3\\1,1,5&5\\& \overline{2^{3}\times3^{2}\times5=8\times9\times5=\textbf{360}}\\ 1,1,1\end{array}$

Final result : 360 is the least common multiple.

I hope I have collaborated !
