# 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 will be using the concept of LCM(Least Common Multiple) to solve this.

To find the minimum distance each should cover so that all can cover the distance in complete steps, we have to find the LCM of 63, 70, 77.

LCM = 2 × 3 × 3 × 5 × 7 × 11 = 6930

Hence, the minimum distance each should cover so that all can cover the distance in complete steps is 6930 cm.
