They will again meet at the lowest common multiple of 80, 85 and 90 cm
80 = 2*2*2*2*5
85 = 5*17
90 = 2*3*3*5
So, LCM of 80,85 and 90 will be
= 2*2*2*2*3*3*5*17
=16*9*5*17
=12,240
So, they all three will meet after 12,240 m
80 = 2*2*2*2*5
85 = 5*17
90 = 2*3*3*5
So, LCM of 80,85 and 90 will be
= 2*2*2*2*3*3*5*17
=16*9*5*17
=12,240
So, they all three will meet after 12,240 m
