n. Since n is composite, there exists an integer e in the range 1 < e < n such that e|n. Then ef = n for some integer f. Since f is also a positive divisor of n, it follows from our assumption that e > √ n and f > √ n. (Note that we cannot have f = 1 because e < n and we cannot have f = n because e > 1). But then n = ef > √ n √ n > n is ...
