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
The LCM of the size of the steps of the three boys will give the minimum distance that each should cover so that all can cover the distance in complete steps
LCM of 63 cm, 70 cm and 77 cm will be 2*3*3*5*7*11
= 6930 centimeter
Hence, minimum distance walked y the three boys is 6930 centimeter
