## Initialize this cell to create a B-factoring function

Run this cell to set up the B-factoring capability. Choose your factor base on the first line.

## B-factor all numbers in a list (initialize cell above first)

## Take a gcd

## Just in case you want this: Solve quadratic congruences (or other equations) mod n
