Detailed Solution

Here we are given that the first boy's steps measure = 63 cm

The second boy's steps measure = 70 cm

The third boy's steps measure = 77 cm

To find the minimum distance we need to calculate LCM of 63, 70, 77

NCERT solutions for Class 6 Maths Chapter 3 Exercise 3.7 - 3

LCM = 2 × 3 × 3 × 5 × 7 × 11 = 6930

Therefore, 6930 cm is the distance that each boy needs to travel in order for all to cover the distance in complete steps.
