Those are commonly used for working with fractions. You need the least common multiple to find a common denominator, for adding or subtracting fractions. And after doing some manipulations with fractions, you need the greatest common factor to simplify the fractions.
Now, whether this is sufficiently "real-life" for you, is another issue. Depending on the career you choose, you many need to work with fractions on a daily basis, or you may hardly ever need them.

In a non-academic, practical setting the LCM is used when unlike fractions are added or subtracted, like when a carpenter has to add measurements of eights and sixteenths.
Adding or subtracting fractions requires the use of a common multiple. It is rare that the LEAST common multiple is required - it is useful to keep the numbers small and manageable.
The LCM of 3 and 6 is 6 The LCM of 5 and 7 is 35. The LCM of 8 and 9 is 72. The LCM of 12 and 15 is 60.
7 can divide into the LCM of some sets of numbers, not others.
The LCM of 2 and 3 is 6. The LCM of 2 and 4 is 4. The LCM of 5 and 7 is 35. The LCM of 7 and 9 is 63.
We use the LCM to find the least common denominator of unlike fractions.
You would use it when adding fractions.
