Question : 26 of 40

Marks: +1, -0

Find the LCM of

6/5,5/4,4/3\and3/2 .

Solution:

The LCM of a fraction

={ \LCM \of \Numerator}/{ \HCF \of \Denominator }

LCM of

6/5,5/4,4/3\and3/2

={ \LCM \of (6,5,4,3)}/{ \HCF \of (5,4,3,2)}

LCM of 6, 5, 4 and 3 = 60
HCF of 5, 4, 3 and 2 = 1
So, LCM of

6/5,5/4,4/3\and3/2 =60/1=60
