Given numbers are,

Also, written as

Now, remove the decimals from the above numbers they will be

Using prime factorisation method, Factors of the following numbers are

Now, as we know that H.C.F is the product of common factors of the all the numbers

And L.C.M is the product of factors with highest power in all the numbers.
Highest power of

are

respectively
Therefore,

Now, put the decimal in numbers and L.C.M, H.C.F
The L.C.M and H.C.F of

are

respectively.
Hence, the correct answer is option (1) .
