Three boys step off together from the same spot. Their steps measure 63 cm, 70 cm and 77 cm respectively. What is the minimum distance each should cover so that all can cover the distance in complete steps?
Solution:
We need to find value of L.C.M of 63, 70 and 77 which would be the minimum distance each should cover so that all can cover the distance in complete steps.
Therefore, L.C.M of 63, 70 and 77
Therefore, 6930 cm is the minimum distance each should cover so that all can cover the distance in complete steps.
