Rational-function simplification is key bottlenecks in integration-by-parts (IBP) reduction of Feynman integrals. We study denominator factorization patterns appearing in IBP coefficients and develop practical algorithms for extracting and exploiting factorized denominator structure within the FUEL interface. The resulting workflow reduces reconstruction cost and improves robustness of large-scale reductions.
