You can find a common denominator of any set of denominators by multiplying them together. That result will not necessarily be the lowest common denominator. Example: 1/6 and 1/9 6 x 9 = 54 and 54 is a common denominator of 6 and 9, but the LCD is 18.

The easiest way to find a common denominator of two numbers is to multiply them. Therefore, one of the common denominators for 6 and 7 would be 42 (7 x 6). This method will not necessarily produce the lowest common denominator, but it will determine one. For example, multiplying 4 and 6 will give you 24 as a common denominator. However, the lowest common denominator for 4 and 6 is 12.
6 the lowest common denominator is the least common multiple of the denominators after both fractions have been simplified as far as possible. 3/6 can be simplified as 1/2. 2/3 cannot be simplified any further. The LCM of 3 and 2 is 6, so the lowest common denominator is 6.
