Is there a simple way to solve a linear congruence modulo an integer with large prime factors in Sage? solve_mod function cannot handle such large moduli apparently.

"WebI have tested and compared a few methods of computing modular powers. Apart from SageMath's power_mod, I have tried Python's pow, GMP's .powermod and SageMath's modular integer rings. The latter three have noticably outperformed power_mod, but all of them gave improvements of order of 30%, as opposed to 70% provided by Julia (tested … " - Sagemath mod function
