LCD means lowest (or least) common denominator, and that implies there must be at least two fractions involved for something to be common to both of them. There is, therefore, no sensible answer to this question.
The LCD of 13, 14 and 15 is 2730 The LCD of 1/3, 1/4 and 1/5 is 60
105
LCD(15, 11) = 165.
The LCD of 3,5 and 15 is 15 because they can all go into 15!
To find the least common denominator (LCD) of the fractions 14/15 and 11/12, first identify the denominators: 15 and 12. The prime factorization of 15 is 3 × 5, and for 12, it is 2^2 × 3. The LCD is found by taking the highest power of each prime factor: 2^2 (from 12), 3 (from both), and 5 (from 15). Thus, the LCD is 2^2 × 3 × 5 = 60.
LCD(15, 26) = 390
LCD(9, 15) = 45
LCD(15, 7, 8) = 840.

LCD refers to integers. The LCD of 15 and 23 is 345
The LCD of x, 5, 7, 15 is 105x.
