Which of the following CANNOT be the least common multiple of two positive integers x and y
Select the correct option
A) xy	B) x	C) y	D) y - x^2	E) x + y
The least common multiple of two positive integers cannot be less than either of them. Therefore, since y - x^2 is less than x, it cannot be the LCM of a x and y.   Answer: y - x^2
