Morphology
The meaning is directly and compositionally derived from 'prime' (a number divisible only by 1 and itself) modifying 'quantity' (a numerical magnitude) — i.e. a quantity that is prime. This follows a standard modifier+head composition pattern, so a B1 learner who knows both constituent meanings can infer the intended sense even if the collocation 'prime number' is more idiomatic.
Etymology
The noun prime quantity creates a clear image: prime means 'first' or 'special' and quantity means a number, so a prime quantity is a number that can only be divided by 1 and itself.
