since 9 friends visit everyday, second day,------, 9th day.
1. since 2nd friend visit on second day so they will meet together on even day number.
2. since 3nd friend visit on third day so they will meet together on even day number that will be the multiple of 3.
so for all we will have to the same process so we will take the L.C.M of all days 1, 2, 3, 4, 5, 6, 7, 8, 9 = 2520
so they will meet together on 2520th day
