You use the LCM when you want to add or subtract fraction and then you can use the HCF to simplify the result.
You may want to do this when budgeting: for example one quarter of your pay goes on rent, two fifths goes on food and drink, and so on. So how much of your pay is available for discretionary spending?
In finding the LCM or HCF of two or more numbers

LCM is 20 and the hcf is 10
For the division of quantities
LCM is used to find the lowest common denominator in fractions HCF is used to reduce fractions to their simplest terms
HCF = 3... LCM = 18 !
HCF is 60 and the LCM is 360
HCF is 48 and LCM is 576
hcf = 42, lcm = 84.
The HCF is: 2The LCM is: 2,520
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.
