Are 224 and 243 relatively prime?

Answer 1

A single number, such as 224243 cannot be relatively prime. And if they are meant to be two numbers, then we cannot tell whether they are meant to be2 and 24243

22 and 4243

224 and 243

2242 and 43

or 22424 and 3.

However, you will be pleased to know that the answer is the same in all cases: they are coprime.

Answer 2

Yes, because they do not share any of the same prime factors other than 1.

224 = 2 x 2 x 2 x 2 x 2 x 7

243 = 3 x 3 x 3 x 3 x 3
