18 and 3
6 and 36 12 and 18
The two numbers that have a least common multiple (LCM) of 54 and a highest common factor (HCF) of 3 are 27 and 18. The LCM is the smallest common multiple of the two numbers, while the HCF is the largest common factor. In this case, 27 and 18 have a LCM of 54 (27 x 2) and a HCF of 3 (3 x 3).
6 and 18
HCF of 12 and 18 is 6 and LCM of 108 and 72 is 216 So: 6 times 216 = 1296

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.
