least common denominator it means what number both fractions can divide evenly into ex. 2/8 and 4/16 they simplify to 1/4 because 8 and 16 simplify to 4
p.s. I'm only in middle school so don't take this to seriously

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.
Multiplying the denominators together of two or more unlike fractions will get you a common multiple.
There is none because the Least Common Denominator (or LCD) refers to the Least Common Multiple (LCM) of the denominators of two or more fractions or mixed numbers. Even if you converted your whole numbers (x) to their fraction equivalents (x/1), the LCD would always be 1.

I am not entirely sure what you mean, but if you need to add, subtract, or compare two fractions, they need to have the same denominator.
