pg 55 prop 2.4 O not P- Liam

In number theory 2 just before section 3 on primes and the fundamental theorem, there are some details missing: a’=a/gcd (a,b) and we have a’ divides b’y implies y’=a’k because

so if a'|b'Y and a' is coprime with b' then by bezout we can get a'x+b'y=1, so Ya'x+Yb'y=Y and the left hand side is divisible by a'
