Three boys step off together from the same spot. Their steps measure respectively. What is the maximum distance each should cover so that all can cover distance in complete steps?
Here, the required minimum distance will be equal to the LCM of measures of their steps.
Given,
Step measure of st boy
Step measure of nd boy
Step measure of rd boy
Find the LCM of all boys steps:
LCM of
Hence, the minimum distance each should cover so that all can cover the distance in complete steps is .
