See the question code carefully, CL**LCM** which simply means find the *LCM of the array* input and it should be *odd not even* and now if you want to know that array can produce odd or not so simply know that any number which is even will give an even number so you can run a loop finding that even numbers in the array and if no even numbers are found print yes.
