Answer 1

lcm of 50,100 = 500 500 kilometre they will stop together

Answer 2

Given :

Three Haryana Roadways buses stop after 50, 100 and 125 km respectively.

To Find :

If they leave together, then after how many kilometers they will stop together?

Solution:

We are given that Three Haryana Roadways buses stop after 50, 100 and 125 km respectively

Now we are supposed to find . If they leave together, then after how many kilometers they will stop together

So We need to find LCM

5 |  50 , 100 , 125

5 |  10,20,25

5 | 2 , 4, 5

2 | 2 ,4,1

2 |  1 , 2 ,1

  |  1 ,1 ,2

$LCM = 5 \times 5 \times 5 \times 2 \times 2$

LCM = 500

Hence They will stop together after 500 kilometres
