Question

In a morning walk, three persons step off together. Their steps
measure 80cm, 85cm, and 90cm. What is the
minimum distance each should walk so that all can cover the
same distance in complete steps? (Use prime factorization
method)

Answer 1

7310 cm

Step-by-step explanation:

Their steps = 80 cm

85 cm

90 cm

For finding minimum distance = LCM

LCM of 80 , 85 and 90 = 7310

therefore minimum distance covered = 7310 cm
