380 = 2 * 2 * 19 * 5
18 = 2 * 3 * 3
As u can see that HCF(18) is not a part of LCM i.e there are no 3's in it.
Therefore, this is not possible!.
Hope it helps!

Answer:
this is a very nice question
the question is "can two number have 18 as their hcf and numbers 380 as their lcm?"
so for solving this sum ,we must recall a property..............
→ lcm is a mutiple of hcf ←
here , we see that 380 is not multiple of 18
∴two no. cant have 18 as their hcf and numbers 380 as their lcm.
