@All.
Here we want to know if 0.9 is the HCF or 0.18 is.
I think both the numbers are found to be factors of 0.9, 1.08 and 0.36. But since we need the HCF (Highest common factor), the highest value among them should be 0.9 between 0.9 and 0.18.
Hence I think 0.9 is the highest common factor of 0.9, 1.08 and 0.36.
Correct me if wrong, please.

Firstly, do subtraction from the first two numbers (108 - 36 = 72) .
Next, do subtraction of next two numbers(36-90=54)"- sign have no value".
next, subtract first and last numbers(108-90).
Then, subtrac the first Answers(72 - 52 = 18).
So, the answer is 18.

GCD (Greatest Common Divisor) is just another term for HCF.
Just turn the given numbers 1.08, 0.36, 0.9 into 108/100, 36/100, 90/100
And find the HCF of 108, 36, 90 which is equal to 18.
And divide this answer 18 by 100,
We get 0.18.

0.9 value is greater than 0.18 and it is a common divisor for 1.08, 0.36 and 0.9.
So, the answer should be 0.9 right?

No, if you divide 0.36/0.9 = 0.4.
ie, not a whole number which means it not divisible by 0.9.

if you convert 0.9 as 9/10 then 0.18 is not the answer and if you convert 0.9 as 9/100 then you get 18 as 0.18.
And between both numbers greater is 0.9 as you are finding the gcd.
