18 and 3
They are 9 and 6
6 and 36 12 and 18
6 and 18
The HCF of the numbers 18 and 40 is 2.
HCF of 12 and 18 is 6 and LCM of 108 and 72 is 216 So: 6 times 216 = 1296
3 and 18

They are 9 and 6

3 and 18 do.
HCF = 3... LCM = 18 !
Factors: 15 = 3 x 5, 18 = 2 x 3 x 3. The LCM of two numbers = their product divided by their HCF. In this instance the product is 270 and the HCF is 3 so the LCM is 90.
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.
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.
