Parachutists

During freefall, parachutists were first held in groups of 4, then 6, then 9, 12, and finally 18 members. If each group must all be involved, how many parachutists must jump at least?

Correct answer:

n =  36

Step-by-step explanation:

4=22 6=23 9=32 12=223 18=232 LCM(4,6,9,12,18)=2232=36  n=LCM(4,6,9,12,18)=36
