Yes, we can have 10 as HCF and 300 as LCM of any two natural numbers.
This is explained as follow :-
In mathematics, there is a rule that thej HCF of any two number must be a factor of LCM or LCM must be a multiple of HCF.
i.e. LCM ÷ HCF gives remainder zero
If this is not satisfied then the given condition is wrong.
e.g.
Two numbers can have 12 as LCM and 4 as HCF because 12 is divisible by 4 while two numbers cannot have 16 as LCM and 3 as HCF because 3 is not factor of 16.
Now in the question
HCF is a factor of LCM i.e. 10 is a factor of 300
Hence two numbers can be exist i.e. real number because it satisfy the condition.
