HCF of 3 means the numbers both have a prime factor of 3. LCM of 12 means that, between the numbers, there are factors of 2, 2 and 3. But these 2s cannot be shared, else the HCF would be greater. Therefore, the numbers will need to be 3 and 2x2x3, or 12.
The LCM is the higher number. The LCM of 9 and 18 is 18.
The LCM of 54 and 24 is 216.The Least Common Multiple (LCM) for 54 24 is 216factoring24=2*2*2*354=2*3*3*3so LCM =2*2*2*3*3*3=216
The LCM is 18.
You need at least two numbers to find an LCM.
To find the HCF you first need to express the numbers as products of their prime factors. In this case we have: 18 = 2x3x3 70 = 2x5x7 The next step is to identify any common prime factors. In this case, both numbers have a 2 as a prime factor. Thus the HCF is 2. To find the LCM, you simply multiply the numbers together and divide by the hcf: 18x70/2 = 630 So the LCM is 360.
18 and 3
3 and 18
12 and 18
They are 9 and 6
6 and 36 12 and 18
3 and 18 6 and 9
6 and 36 12 and 18
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.
