Question

Can two numbers have 18 as their HCF and 380 as their LCM? Give reason.​

Answer 1

Answer:

The LCM of a number must be divisible by its HCF. So , if 18 is the HCF and 380 is LCM,

Then, 380 must be divisible by 18.

380/18= 190/9

which means that the statement is wrong and 1880 are not the HCF and LCM respectively .

hope it helps..
