Problem:
Determine, with proof, whether or not there exist positive integers , , and such that
Solution:
The answer is no. Note that has exactly one prime factor of . Therefore, exactly one of , , and is divisible by . If divides (we write this as ), then but , so the equation cannot hold. Likewise, if , then , but , and if , then , but . So there are no solutions.
