Solution 1 Working with the second part of the problem first, we know that has divisors. We try to find the various possible prime factorizations of by splitting into various products of or integers. WebFinal answer. Step 1/3. First, we will prove that if a positive integer n is composite, then ϕ ( n) ≤ n − n. Let n be a composite integer, which means it has at least two distinct prime factors. Let p and q be two distinct prime factors of n, such that p ≤ q. Then, we have: n = p q ≥ p 2. Taking the square root of both sides, we get:
