3,2.7,0.09 can be written in fraction form as
3/1, 27/10, 9/100
since, L.C.M of two or more fractions is given by L.C.M of numerators/ H.C.F of denominators ( A/c to how to prepare for Quantitative Aptitude for CAT by ARUN SHARMA page no.:-26 fifth edition)
LCM of numerators 3,27,9 is 27
HCF of denominators 1,10,100 is 1
therefore , 27/1

Piyush Telang   9 years AGO

LCM of 3, 2.7, 0.09 is calculated as fractions
=> 300/100 , 270/100, 9/100
=> LCM of numerators / HCF of Denominators
=> 2700 / 100 => 27
Thus LCM of 3, 2.7, 0.09 is 27

3, 2.7, .09

Now, expressing each of the numbers without the decimals as the product of primes we get

300 = 3 × 2 x 2 x 5 x 5

270 = 3 x 3 x 3 x 5 x 2

9 = 3 x 3

L.C.M. of 300, 270, 9 = (2^2) x (3^3) x (5 ^2) = 4 x 27 x 25 = 2700

Therefore, L.C.M. of 3, 2.7, .09 = 27.00 (taking 2 decimal places)
