Morphology

high + common + factor

The phrase is compositionally built: 'factor' (a number that divides another), 'common' (shared by the given integers), and 'highest' (the largest). A B1 learner who knows these constituents can derive that it means the largest number that divides all the given numbers; this is a standard mathematical collocation with cross-linguistic parallels, so the sense is predictable from the parts.

Etymology

Highest common factor comes from a simple picture: imagine you have two groups of objects and you want to make equal piles using the biggest pile size that works for both. The word factor means a number that 'goes into' another number, common means it is shared by both numbers, and highest means the biggest one, so the phrase means 'the largest number that goes into each of the given numbers without leftovers'.
