You need at least 2 numbers to get a lowest common denominator. The lowest denominator for 238 is 1, but as there is no other number in the question, there is no common denominator.
The lowest common FACTOR of 7,3 and 2 is 42.
First, you have to have a lowest common denominator. Eg: 1/2 - 6/13 The lowest common denominator is 26, because 13 * 2 is 26. You multiply 1/2 by 13, to make the denominator 26, which equals 13/26, then multiply 6/13 by 2 to get 12/26. So the equation with the lowest common denominators now plugged in is: 13/26 - 12/26 Subtract the numerators (13 and 12), so the answer is 1/26.
