WebThe set of integers is denoted Z (from the German word Zahl = number). 2. The Divisibility Relation De nition 2.1. When a and b are integers, we say a divides b if b = ak for some k 2Z. We then write a jb (read as \a divides b"). Example 2.2. We have 2 j6 (because 6 = 2 3), 4 j( 12), and 5 j0. We have 1 jb for every b 2Z.

WebIf n is even, then 2 n − 1 is divisible by 3, so 2 n − 1 cannot divide 3 n − 1 unless n = 0. So let n > 1 be odd. Let p be a prime that divides 2 n − 1. Then since 2 n ≡ 1 ( mod p), the order of 2 modulo p is odd, so 2 is a quadratic residue of p. If furthermore 2 n − 1 divides 3 n − 1, then 3 n ≡ 1 ( mod p), and therefore 3 is ...
