Well you can always multiply them. For example, x(x+2) would give you a common denominator of both x and x + 2. However, that will not always
give you the least common denominator.
To find the least common denominator of x and x + 2, you can use a simple formula I just thought of in my head.
If x is even:
(x^2/2) + x
If x is odd:
x^2 + 2x
For example, if x was 6, and x + 2 was 8...Then the common denominator, based on the 1st formula would be (6^2)/2) + 6 = 18 + 6 = 24.
If it was 5 and 7. Based on the 2nd formula, since x is odd, it would be 35.
I believe these are correct.
