The LCD of 13, 14 and 15 is 2730
The LCD of 1/3, 1/4 and 1/5 is 60
LCD(14, 19, 15) = 3990
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.
The average mean is: (11+12+13+14+15)/5 = 13
15 = 1111 14 = 1110 13 = 1101
13 is prime.
LCD(21, 13, 14, 15) = 2730
