If 16 and 19 are denominators, their LCD is 304.
If that's 1/6 and 1/9, the LCD is 18.
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.

38 is.

It is 76
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions.
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions.
lcd(8, 19) = 152.
It is: 1330
133
It is: 95
19 is prime, so multiply 19 by 112.
LCD(19, 14) = 266.
