Hmm... Isn't it more precise to say "they share no common prime factors" or "they share no common factors besides 1?".

Well to think of the matter we need to look at it from the Greatest common factor point.

2,3 share no factor and are only divisible by 1

1 is a factor of any number

It is in this form GCF(n, n+1) = 1

I hope this helps.
