Question

three boys step off together from the same spot. their steps measure 63 CM, 70 cm, 77 CM respectively. what is the minimum distance of each should be covered so that all can cover the distance in complete steps?​

Answer 1

Answer:

6930 CM

Step-by-step explanation:

Here, the required minimum distance will be equal to the LCM of measures of their steps.

Step measure of 1st Boy = 63 cm

Step measure of 2nd Boy = 70 cm

Step measure of 3rd Boy = 77 cm

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.
