Answer:
Around a circular path of 360 km, three men start walking , say A at 48, B at 60 and C at 72 km per day. After how many days will they meet?
answer ,
The prime factors of
48 = 2x2x2x2x3
60 = 2x2x3x5
72 = 2x2 x2 x3 x3
LCM = 2x2x2x2x3x3x5 = 2^4x3^2x5 =720
The three will meet at the starting point after A man for 720/48 = 15 days, B man for 720/60 = 12 days and C man for 720/72 = 10 days
