Abstract: A real arrangement of affine lines is a finite family $ \mathcal{A}$ of lines in $ {{\mathbf{R}}^2}$. A real arrangement $ \mathcal{A}$ of lines is said to be factored if there exists a partition $ \Pi = ({\Pi _1},{\Pi _2})$ of $ \mathcal{A}$ into two disjoint subsets such that the Orlik-Solomon algebra of $ \mathcal{A}$ factors according to this partition. We prove that the complement of the complexification of a factored real arrangement of lines is a $ K(\pi ,1)$ space.
