What is the LCM of 18 and the hcm of 3?

Answer 1

LCM=18=2*32

HCF(guess that is what u meant, highest common factor)=3

Possibilities: 3 and 18, 6 and 9, three or all of the numbers together.

Note:

3 and 6 gives a LCM of 6

3 and 9 gives a LCM of 9

6 and 18 gives a HCF of 6

9 and 18 gives a HCF of 9

Three or four out of the numbers (3,6,9 and 18) will give you LCM of 18 and HCF of 3 as well.
