Question

There is a circular path around a sports field. Priya takes 18 minutes to drive one round of the field. Harish takes 12 minutes. Suppose they both start at the same point and at the same time and go in the same direction. After how many minutes will they meet? WHY SHOULD WE FIND THE LCM AND NOT HCF IN THIS CASE?
