Question 566914: John, Paul, George, and Stuart were four school friends. After one particularly hard day's night, they went to see a movie together. After the first time, they began going regularly but on different schedules. (They even went on weekends.) John went every fourth day, Paul went every fifth day, George went every seventh day, and Stuart went every ninth day. How many days was it before all four went to the movies together again?
Thanks

:

The numbers do not have any common prime factors, therefore
4*5*7*9 = 1260 days before they all went to the movies together again
