You don't. LCM and GCF (HCF) refer to whole numbers. You can find the LCM of two whole numbers that happen to be denominators, but in that case we call it the LCD. You can find the GCF of two whole numbers that happen to be the numerator and denominator of a fraction, and that will let you know whether the fraction can be simplified.
The LCM is used for integers, not fractions. If you're trying to add unlike fractions, take the LCM of the denominators (known in this case as the least common denominator, or LCD), convert the fractions and proceed.
Finding an LCM will help when you want to add and subtract fractions.
The concept of LCM is not applicable to fractions. This is because all numbers are evenly divisible by all non-zero numbers and all numbers are multiples of all non-zero numbers.
Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).
3/5 and 3/20you need to find the LCM of 5 and 20 multiples of 5: 0,5,10,15,20 multiples of 20: 0,20,40,60,80 the LCM of thedenominators,5 and 20, is 20

When adding fractions, you want to make sure that the denominators are the same. It's the same process as the LCM.
We use the LCM to find the least common denominator of unlike fractions.
Finding the LCM helps in the process of adding and subtracting unlike fractions.
To add and subtract fractions, you need common denominators. To find the common denominator, find the LCM of the denominators you wish to add or subtract.
LCM is used to find the lowest common denominator in fractions HCF is used to reduce fractions to their simplest terms
Because to add fractions, the denominators must be equal.
The LCD of two fractions is the same as the LCM of their denominators.
