## Task 2 - V00602

Five working groups of a school meet on July 1st to discuss their vacation plans.

They decide that the biologists will meet every second day, the physicists every third day, the geographers every fourth day, the model builders every fifth day, and the electrical engineers every sixth day. On the day when all groups meet again simultaneously at the school, they want to evaluate their work.

When is this day, if the groups meet regularly (also on Sundays) starting from July 1st?
The working groups meet again when the number of days is divisible by 2, 3, 4, 5, and 6. This means the number of days sought is the least common multiple of 2, 3, 4, 5, and 6, i.e., 60. The students meet again after 60 days, i.e., on August 30.
