Only 1.
It is not possible to express something as a sum of whole numbers with no common factor. All whole numbers have at least 1 as a common factor.
The least (meaning lowest) common factor of any set of whole numbers is always 1. The greatest common factor of any set of whole numbers will depend on the factors of the individual whole numbers in the set.

The least common factor of any set of numbers is 1.
common factor
1 is a factor of every whole number, and the gcf of two numbers can be 1 if there is no larger factor common to both numbers.
The least common factor of any set of integers is 1.
You must have at least two whole numbers to determine a greatest common factor.
