Question

can two numbers have 18 as their HCF and 694 as their LCM ? given reason​

Answer 1

no HCF and LCM has to all common factor

Answer 2

No. This isn't possible.

Take 2 numbers 6 and 24. Their HCF is 3 and their LCM 48. Here, you can see that the HCF is always a factor of the LCM. Remember this...

But in this case 18 isn't a factor of 694. Hence, the given case is false.
