Both oobleck and i stated that we don't understand your actual question.

I don't expect you to follow the steps of how I found that highest
common divisor which leaves the same remainder, but I gave it to you

k = 439, common remainder = 362

Don't know what else you want us to do.

Answer 2

mathhelper's little BASIC program divided the numbers by 1,2,3... until a common remainder was found. You could just as easily iterate by subttracting 1,2,3... from the numbers, and then finding the GCF of the diminished numbers. When the GCF is greater than 1, then you have found your answer.
