lapo4ka [179]

Answer:

60 weeks

Step-by-step explanation:

Factor both numbers 12 and 15:

  • 12=2\cdot 2\cdot 3;
  • 15=3\cdot 5.

Find LCM(12,15). The common factor is only 3, multiply ths common factor by all factors that remain. Then

LCM(12,15)=3\cdot 2\cdot 2\cdot 5=60.

This means that the fewest number of weeks that will pass before both machines are cleaned again in the same week is 60 weeks.
