Question

LCM of 0.24, 1.8, 2.7 and 6 is​

Answer 1

Answer:

We first convert the given decimals 3.6,0.24,1.2 into like decimals as 3.60,0.24,1.20

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

360=2×2×2×3×3×5

24=2×2×2×3

120=2×2×2×3×5

Now, HCF of 360,24 and 120 is 2×2×2×3=24

Therefore, HCF(3.6,0.24,1.2)=0.24 (taking 2 decimal places)

And LCM of 360,24 and 120 is 2×2×2×3×3×5=360

Therefore, LCM(3.6,0.24,1.2)=3.6 (taking 2 decimal places)

Hence, the HCF and LCM of 3.6,0.24,1.2 is 0.24 and 3.6 respectively.
