Let a and b be positive integers. A common multiple of a and b is an integer N such that a and b both divide N . The least common multiple of a and b is the smallest positive common multiple of a and b. It is denoted by LCM(a, b). 26. Prove that a and b have a least common multiple. 27. If a has a prime factorization given by a = p1k1 · · · prkr , prove that any positive multiple M of a has a prime factorization given by a = p1m 1 · · · prm r q1n 1 · · · qsn s , where q1 , . . , qs are primes not in the list p1 , .
PROOF. Conclusion (a) is immediate from the deﬁnition. For (b), let σ = τ1 · · · τk with each τ j equal to a transposition. 23 recursively, using (a) at the end: sgn(τ1 · · · τk ) = (−1) sgn(τ1 · · · τk−1 ) = (−1)2 sgn(τ1 · · · τk−2 ) = · · · = (−1)k−1 sgn τ1 = (−1)k sgn 1 = (−1)k . 22 shows that any permutation is the product of transpositions. If σ is the product of k transpositions and τ is the product of l transpositions, then σ τ is manifestly the product of k + l transpositions. Thus (c) follows from (b).
Many readers will already be familiar with some aspects of this theory, particularly in the case of the vector spaces Qn , Rn , and Cn of column vectors, where the tools developed from row reduction allow one to introduce geometric notions and to view geometrically the set of solutions to a set of linear equations. Thus we shall 33 II. Vector Spaces over Q, R, and C 34 be brief about many of these matters, concentrating on the algebraic aspects of the theory. Let F denote any of Q, R, or C. 1 A vector space over F is a set V with two operations, addition carrying V × V into V and scalar multiplication carrying F × V into V , with the following properties: (i) the operation of addition, written +, satisﬁes (a) v1 + (v2 + v3 ) = (v1 + v2 ) + v3 for all v1 , v2 , v3 in V (associative law), (b) there exists an element 0 in V with v + 0 = 0 + v = v for all v in V , (c) to each v in V corresponds an element −v in V such that v + (−v) = (−v) + v = 0, (d) v1 + v2 = v2 + v1 for all v1 and v2 in V (commutative law); (ii) the operation of scalar multiplication, written without a sign, satisﬁes (a) a(bv) = (ab)v for all v in V and all scalars a and b, (a) 1v = v for all v in V and for the scalar 1; (iii) the two operations are related by the distributive laws (a) a(v1 + v2 ) = av1 + av2 for all v1 and v2 in V and for all scalars a, (b) (a + b)v = av + bv for all v in V and all scalars a and b.
