Best Answer

In the case of multiplying 1234 by 4567, the divide and conquer method is no more than what you would do to multiply them on a piece of paper.

Start with 4 x 7, giving 28.
Continue with 4 x 6, giving 24, shifted left to give 240, and then added to 28.
... and etc.

In the end, you have multiplied 16 times, and added the partial products together to get a final result.
