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.
LCM of 14 12 28 is 84
The LCD of 1/4 and 1/6 is 12
LCD(12, 14, 16) = 336.
6/12 + 8/12 = 6+8/12 = 14/12 = 7/6 = 11/6
11 over 14 is 11/14 in its lowest terms (11 and 14 have no common factor other than 1).

It is: 462
11/12 + 3/12 = 14/12 = 7/6 or 1 and 1/6
LCM of 14 12 28 is 84
LCD(11, 16) = 176
The LCD of 1/4 and 1/6 is 12
You need at least two fractions to find an LCD.
LCD(12, 14, 16) = 336.
