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.

How do you find the LCM multiple for two fractions?
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.
Why should you find a LCM?
Finding an LCM will help when you want to add and subtract fractions.
How can you find the LCM of two 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.
Explain how comparing fractions with like denominators differs from comparing fractions with unlike denominators?
Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).
How do you find the LCD of algebraic fractions?
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
Find the LCM 0.631.052.1?
The LCM refers to whole numbers, not fractions.
How do you find the LCM multiple for two fractions?

Why do you needto find the LCM?
Finding the LCM will help you when you need to add and subtract fractions.
Why should you find a LCM?
Finding an LCM will help when you want to add and subtract fractions.
Do you find the GCF or LCM when adding fractions?
When adding fractions, you want to make sure that the denominators are the same. It's the same process as the LCM.
What are some uses of the LCM?
We use the LCM to find the least common denominator of unlike fractions.
Why do you find the LCM of numbers?
Finding the LCM helps in the process of adding and subtracting unlike fractions.
How is finding the LCM revelant when adding and subtracting 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.
Examples for LCM and HCF we use in daily life?
LCM is used to find the lowest common denominator in fractions HCF is used to reduce fractions to their simplest terms
IS THE LCD OF TWO FRACTIONS THE SAME AS THE LCM NUMERATORS AND FRACTIONS?
The LCD of two fractions is the same as the LCM of their denominators.
What is the LCM for 3.14 and 1.7 in fractions?
The LCM refers to integers, not fractions.
When you add or subtract fractions with unlike denominators why do you have to find LCM?
Because to add fractions, the denominators must be equal.
