Question

Three boys start walking with their first step together from the same place. The measure of their steps are 60 cm, 72 cm and 75 cm respectively. Find the minimum distance from the starting place where their steps will be together again.​

Answer 1

Answer:

Here, the required minimum distance will be equal to the LCM of measures of their steps.

Step measure of 1st Boy = 63 cm

Step measure of 2nd Boy = 70 cm

Step measure of 3rd Boy = 77 cm

LCM of 63,70,77

LCM=2 × 3 × 3 × 5 × 7 × 11 = 6930

Hence, the minimum distance each should cover so that all can cover the distance in complete steps is 6930 cm.
