I'm looking for what the title says. Euclidean algorithm works and is fast for just a pair of numbers, but I don't see any obvious generalizations. A quick googling didn't turn up anything too ...

Mathematicians have reportedly discovered a new way of multiplying two numbers together. The new technique is for really large numbers, and if it passes a peer-review, could be the fastest ...

It found an algorithm for multiplying two matrices of four rows of four numbers using just 47 multiplications, which outperforms Strassen’s 49 multiplications.

Indeed, when it comes to multiplying two numbers, the best (or fastest) way to do it is often far from obvious. One particularly intriguing and efficient multiplication algorithm was developed in ...
