Question

Can 2 numbers have 18 as their hcf and 380 as their lcm give reasons

Answer 1

Dear....
the HCF of two numbers must be afactor of the LCM . hence the above situation is possible only if 18 is a factor of 380. but we see that it is nota factor of 380. it's not possible to have two numbers whose HCF is 18and LCM is 380...
Hope it helps you out (^^)^_^(^^)
