The least common multiple (LCM) of 5 and 7 is 35, not the least common denominator (LCD). The LCD is used in adding or subtracting fractions and is the least common multiple of the denominators. In this case, since 5 and 7 are prime numbers and have no common factors, the LCD is simply the product of the two denominators, which is 5 * 7 = 35.
The greatest common factor of 50 and 65 is 5, since the common factors of 50 and 65 are 1 and 5.
There IS only one LCD. The word least is a superlative, which means there can be only one. LCD(79, 90) = 7110
