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