AB - In the present paper, we will show that the set of minimal elements of a full affine semigroup $A\hookrightarrow \mathbb {N}^k_0$ contains a free basis of the group generated by $A$ in $\mathbb {Z}^k$. This will be applied to the study of the group $\text{\rm K}_0(R)$ for a semilocal ring $R$.
