every day.The second visited every second day.The third visited every third day and so on
upto 9th friend on every 9th day.When will they all meet together?? Explain??

• After 2520 days.
  
  LCM of 1,2,3,4,5,6,7,8,9 is 2520

• 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
