Is it possible to have two numbers whose HCF is 18 and LCM is 760? Give reason.

No, HCF does not divided LCM exactly


Using Euclid’s division lemma -


Take a = 760 and b = 18.


a = bq + r. where q is the quotient, r is the remainder and b is the divisor.


If HCF divides LCM completely, r = 0.


Putting the values -


Here 760 = 18(42) + 4


r = 4


r is not equal to zero


HCF does not divides LCM completely.


So this is not possible for two numbers to have HCF = 18 and LCM = 760.
