Prove that z ∼ nz for n 6 0
WebbClaim: For positive integers n and m we have Z/nZ×Z/mZ ∼= Z/nmZ ⇔ gcd(n,m) = 1. Proof. First off, we make the following observation. Let a ∈ Z/nZ, and consider the element (a,0) … Webbprime, so by the Chinese Remainder Theorem Z/mZ = Z/rsZ ∼= (Z/rZ) × (Z/sZ), so the natural projection Z/mZ → Z/nZ induces a surjection ϕ : (Z/rZ) × (Z/sZ) → Z/nZ. It is enough to show that ϕ is surjective on the units. If x ∈ Z/rZ and y ∈ Z/sZ then ϕ(x,y) = ϕ(x,0), as follows. Since s is relatively prime to n, 1+···+1
