HCF- highest common factor
for two number, their HCF is the largest number which divides both.
LCM- least common multiple
for two number their LCM is the smallest number which is a multiple of both.
now HCF divides both numbers, and both numbers perfectly divides LCM.
so, HCF must perfectly divides LCM.
in other words, for LCM÷HCF remainder must be zero
here, LCM=324
and,HCF=16
clearly, 324/16
=20.25 (remainder is not zero)
thus, there do not exist two number whose HCF is 16 and LCM is 324.
