23 more than 644 is simply, 644+23. and that would equal 667.
There are many ways to do it. You could use long division, plug it into a calculator, count multiples of 23 until they reach 644. One way to work it out is to roughly guess and then correct your answer. For example, here's how I work it out in my head: I know that 644 is roughly 30 times greater than 23. Not exactly, but roughly. 30 * 23 = 690, and 690 is 46 greater than 644. 46 / 23 = 2, so the answer is 30 - 2, or 28.
How about: 23*28 = 644 as one example
Sadly, it is not. 56 is 143.5% more than 23.
