Best Answer

LCM is Least Common Multiple of 2 or more numbers. So, LCM of 1 number i.e. 18 is not defined.

Similarly, HCF is Highest Common Factor of 2 or more numbers. So, HCF of 1 number i.e. 3 is not defined.

What is the LCM and the HCF of 18 and 70?

18 = 2 * 3 * 370 = 2 * 5 * 7Thus:LCM = 2*3*3*5*7 = 630HCF = 2

What is the HCF and LCM of 12 and 15 and 24?

The GCF is 3. The LCM is 120.

What 2 numbers have a HCF of 6 and an LCM of 72 and how?

In these types of problems, the numbers can also be the answer. 6 and 72 have a GCF of 6 and an LCM of 72. Since the product of the GCF and LCM of two numbers is the same as the product of the numbers, you could also use another factor pair of 432, like 18 and 24.
