Otherwise, D - d could be kb where k is a negative integer.<br /><br />And maybe also include d < D in (5a) to make 0 < D - d in (5d) more obvious?2j5khttps://www.blogger.com/profile/15557930348330564784noreply@blogger.comtag:blogger.com,1999:blog-12604614.post-88997879355230587472014-12-16T21:19:12.341-08:002014-12-16T21:19:12.341-08:00This comment has been removed by the author.2j5khttps://www.blogger.com/profile/15557930348330564784noreply@blogger.comtag:blogger.com,1999:blog-12604614.post-23864752319052344182014-12-16T21:16:23.254-08:002014-12-16T21:16:23.254-08:00This comment has been removed by the author.2j5khttps://www.blogger.com/profile/15557930348330564784noreply@blogger.comtag:blogger.com,1999:blog-12604614.post-46548565044971691762011-08-22T06:11:54.942-07:002011-08-22T06:11:54.942-07:00Hi Gustolandia,

The proof does not relate to 1. 1 is the only positive integer that is not composed of primes. <BR/><BR/>In fact, we routinely say gcd(2,3)=1 to show that there is no common prime between two numbers.<BR/><BR/>So, to be more accurate, all integers greater than 1 are composed of a unique set of primes.<BR/><BR/>-LarryLarry Freemanhttps://www.blogger.com/profile/06906614246430481533noreply@blogger.comtag:blogger.com,1999:blog-12604614.post-20077557339627935712008-02-28T14:33:00.000-08:002008-02-28T14:33:00.000-08:00I really do hate to be the devils advocate here, b...I really do hate to be the devils advocate here, but your statement of the theorem indicates that EVERY integer is a product of a unique set of primes. Yet your proof only shows that numbers greater than 1 are products of a unique set of primes.
