can 2 numbers have 16 as their hcf and 320 as their lcm ?

HCF of two numbers is a factor of the LCM of those numbers.

Thus, we cannot have two numbers whose HCF is 16 and LCM is 320.

Because, when we divide 320 by 16, we get a remainder of 0.

Thus, 16 is a factor of 380.

Hence, we can have two numbers whose HCF is 16 and LCM is 320.
