Hi Drdj,

Firstly lets observe the numbers

so we observe that the LCM lacks a term that supplies i.e if had taken the LCM of just 12,45 we would have ended up in

so the least value of x = 16 in that case we have all the factors we would need.

Now other feasible values of x are those that have along with other factors like , ,....,and last(and definitely not the least ) 720 itself so the maximum values of x = 720.

Kalyan.
