6 and 36 12 and 18
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.
2
The HCF of both numbers is 1
It means the highest common factor of two numbers or more. For example the HCF of 18 and 27 is 9 18=2×3×3 27=3×3×3 The common factor is 3×3=9
6 and 36 12 and 18
The GCF is 18.
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.
factors of 8: 1, 2, 4, 8 factors of 18: 1, 2, 3, 6, 9, 18 HCF: 2
18 and 3
3 and 18 do.
The HCF of both numbers is 2
3 and 18
The prime numbers of 2 and 3 are common to 12 and 18 and so 2*3 = 6 which is their highest common factor
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.
To have a HCF, you need at least 2 numbers. There is no HCF in just 1 number.
6 is the HCF of 18 & 48
