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?

Answer :

Step measure of first boy = 63 cm


Step measure of second boy = 70 cm


Step measure of third boy = 77cm


Now calculate the LCM of 63, 70 and 77



LCM = 2 × 3 × 3 × 5 × 7 × 11 = 6930


Therefore,


The maximum distance each should cover so that all can cover the distance in complete steps is 6930 cm.
