The same as finding the LCM. Example 1/30 and 1/42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Combine the factors, eliminating duplicates.
2 x 3 x 5 x 7 = 210, the LCD
Least common denominator.....
They are useful in finding the least common denominators.
The process of finding the LCM is the same as finding the least common denominator which is important when you want to add and subtract fractions.
finding the least common denominator formula
No.

to find the least common multiple of two numbers you must list the factors then you can find out their least common multiple of the two numbers
In general, the two are not related.
It is a method of finding the LCM (Least Common Multiple) of 2 or more numbers. Suitably used for finding the least common denominator when adding/subtracting fractions.
There is no "most common multiple". To find all common multiples, you start by finding the least common multiple. All other common multiples are multiples of this least common multiple.
It is always possible.
