Question

Find the L.C.M.

$0.8,1.6$ and $2.4$

• A. L.C.M. $=3.6$ and H.C.F. $=2.4$
  
• B. L.C.M. $=2.4$ and H.C.F. $=1.2$
  
• C. L.C.M. $=4.8$ and H.C.F. $=0.8$
• D. L.C.M. $=1.2$ and H.C.F. $=0.4$

Answer 1

Answer: (C)

L.C.M. $=4.8$ and H.C.F. $=0.8$

$0.8=2\times 2\times 2\times 0.1$

$1.6=2\times 2\times 2\times 2\times 0.1$

$2.4=2\times 2\times 2\times 3\times 0.1$

HCF of $0.8,1.6$ and $2.4=2\times 2\times 2\times 0.1=0.8$

LCM of $0.8,1.6$ and $2.4=0.8\times 3\times 2=4.8$

So, correct answer is option C.
