It isn't. 5 - 10 = -5
The positive integers between 4 and 9 inclusive are 4, 5, 6, 7, 8, 9.
The least common factor of any set of positive integers is 1.
It means that given a set, if x and y are any members of the set then x+y is also a member of the set. For example, positive integers are closed under addition, but they are not closed under subtraction, since 5 and 8 are members of the set of positive integers but 5 - 8 = -3 is not a positive integer.
