They are just taken in different order, but that does not influence the result. In other words, the products are equal. But the latter product equals ∏z∈Z/nZ× (a· z) = aΦ(p) · ∏z∈Z/nZ× z. By Invertibility of Products the product ∏z∈Z/nZ× z is invertible, so, multiplying both sides of the above equation by its inverse, we find aΦ(n) = 1. This proves the theorem. 11. The set Z/15Z× contains 8 elements, one of them being 7(mod 15). eqsmod 78 , 494 , 44 , 12 , 1, 15 This in accordance with Euler’s Theorem.

Below the values of the Euler totient function are listed for all positive integers up to 20. 6: Euler totient function 55. 7 (Euler Totient). The Euler totient function satisfies the following properties. 1. Suppose that n and m are positive integers. 25) 2. 26) 3. 27) i=1 4. 29) d∈{d∈N|d|n} Proof. Part (a). Suppose that n and m are two positive integers which are coprime. If a and b are two integers congruent modulo n· m, then they are also congruent modulo n and modulo m. Moreover, if an integer a is relatively prime to n· m, then clearly a is also relatively prime to both n and m.

They turn out to be those nonzero elements which are not invertible. Hence a nonzero element in Z/nZ is either invertible or a zero divisor. 46. 22 (Zero Divisor Characterization). Let n > 1 and a ∈ Z. 1. The class a(mod n) in Z/nZ is a zero divisor if and only if gcd (a, n) > 1 and a(mod n) is nonzero. 2. The residue ring Z/nZ has no zero divisors if and only if n is prime. Proof. The second statement of the theorem is a straightforward consequence of the first. So, we only prove the first. There are two parts to the proof.
