Can you add something here about "pairwise coprime" vs. gcd(a,b,c)=1? user:chas_zzz_brown 17:56 7 Oct 02 (UTC)

[edit] \varphi(1)=1

The definition of Euler's totient function here deviates from the definition in the corresponding article in that the upper inclusive boundary is given as n − 1 instead of n, resulting in a wrong or undefined value for \varphi(1). DirkEn 09:18, 5 September 2006 (UTC)

[edit] probability

The statement about probability of two integers being coprime is fairly misleading at the moment, as nothing has been said about how one chooses two integers "at random". Dmharvey Image:User_dmharvey_sig.png Talk 5 July 2005 18:42 (UTC)

I added some details on the derivation of 6 / π2 and what it means to choose two integers "at random." --Dantheox 20:51, 6 May 2006 (UTC)

[edit] The number "0"

Is the number "0" relatively prime with every another integer? —The preceding unsigned comment was added by 89.0.109.36 (talk) 10:02, 30 January 2007 (UTC).
