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.
A common factor.
A whole number that is a factor of two or more nonzero whole numbers is a common factorThis would be called a common factor.common factor.a common factor

The least common factor of any set of numbers is 1.
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.
common factor
The least common factor of any set of integers is 1.
1 is the least common factor of all whole numbers, so there is nothing to choose for a least common factor. The Greatest Common Factor (GCF) of a set of two or more numbers is the largest factor that will divide into every number in the set without leaving any remainder. 1 is the least, or smallest, factor common to all whole numbers.
