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.
2 x 3 x 3 = 18
3 x 7 = 21
Combine the factors, eliminating duplicates.
2 x 3 x 3 x 7 = 126, the LCM
LCM(Least Common Multiple) as the name suggests is the common multiple of two numbers. Thus, LCM of a single number cannot be found out.
