LCD of 13 and 15 = 195

Step-by-step explanation:

To find the least common denominator, we will find the lowest factor common to both 13 and 15

Prime factorization of 13 = 1 × 13

Prime factorization of 15 = 3 × 5

Both do not have a common factor between them

The LCD = 1 × 3 × 5 × 13

LCD of 13 and 15 = 195
