The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.

No. The LCM MUST be a multiple of the HCF.

In a question how do you know that we have to use HCF or LCM?

Most times the question will specify "find the HCF" or "find the LCM." If you're trying to find common denominators, that's an LCM problem. If you're trying to reduce fractions, that's an HCF problem.

LCM = product/HCF so product = LCM/HCF in this case 380/16 which is 23.75, so the answer to your question is no.
