The context of the question will determine which it is. Also, if you expect the answer to be bigger than the numbers then it is the LCM else the HCF.

Depends on what it is asking for.
Two or more numbers are needed to solve for HCF or LCM.
You cannot. The numbers 2 and 12 have hcf = 2 and LCM = 12 The numbers 4 and 6 also have hcf = 2 and LCM = 12 So if you just knew the hcf and LCM you would not know which of the two was the required pair.
The LCM will never be less than the GCF.
When simplifying fractions it's useful to know what is the HCF of the numerator and denominator is. When adding or subtracting fractions with different denominators it's useful to know what the LCM of them is.
LCM is 20 and the hcf is 10
It's kind of an inverse relationship. The product of the GCF and LCM of two numbers is the same as the product of the original two numbers, so as the GCF increases, the LCM decreases and vice versa. LCM is divisable by HCF.
HCF = 3... LCM = 18 !
HCF is 60 and the LCM is 360
