Morphology

common + denominator

The meaning is directly derivable from combining 'common' (shared) with 'denominator' (the bottom part of a fraction): it denotes a denominator that two or more fractions share for arithmetic operations. This is a compositional noun phrase following standard English logic (and parallels in many languages), so a B1 learner who knows both words will readily understand it.

Etymology

Common denominator comes from a simple math image: a denominator is the bottom number in a fraction and common means shared, so finding a bottom number that all the fractions share links them together. That's why we use common denominator to mean 'a feature or quality that all members share'.
