Easy ans:
Remove decimal points then it become like this way.
108,36,90,then.
108 90 108
36 36 90
--- ---- ----
72 54 18
--- ---- ----
So H.C.F is 18....means 0.18.
I think it fix your problem.

Mehar, can u explain why did u subtract them before calculating HCF?
and the result was not HCF it was LCM.
can u clearly show how LCM vary from HCF?

108 = 18*6
36 = 18*2
90 = 18*5
WE HAVE COMMON FACTOR AS 18 THEREFORE 18 WILL BE IT`S HCF
36 = 18*2
90 = 18*5
WE HAVE COMMON FACTOR AS 18 THEREFORE 18 WILL BE IT`S HCF
