LCD(17, 19) = 323
912
The common denominator is usually the Lowest (or Least) Common Multiple of the numbers involved. Where two numbers have no common factors then the LCM is simply the product of those numbers. As 19 is a prime number and has no factors in common with 18 then the common denominator is 18 x 19 = 342.
You need at least two denominators to find something in common between them.
The Least Common Multiple (LCM) of 79 and 16 is 1,264.
