Over the last century-and-a-half, mathematicians found every possible multiplication table. The largest irreducible multiplication-table, dubbed the Monster Group, contains 808017424794512875886459904961710757005754368000000000 = 2⁴⁶×3²°×5⁹×7⁶×11²×13³×17×19×23×29×31×41×47×59×71 interlocking pieces. That's like the number of atoms in Jupiter.
