Question

Puneet ,arun and manish stat together for a morning walk. Their steps measure 60 cm,84 cm and 108 cm respectively. What is the minimum distance each should walk, so that all can cover the same distance in complete steps

Answer 1

To get the answer u need to get the LCM of 60,84 & 108
their LCM is 3780
So, the minimum distance each should walk, so that all can cover the same distance in complete steps = 3780m

Answer 2

They should be walking  1260 cm in order to cover the same distance in complete steps. This is because:

60= 2*2*3*5 ; 84= 2*2*3*7; 108= 2*2*3*3*3

since, minimum number is asked so, we'll find the LCM

LCM of all the numbers is 1260

therefore, They should be walking 1260 cm in order to cover the same distance in complete steps.
