24 is the least common denominator.
6 = 2 x 3
8 = 2 x 2 x 2 ]
Common factors = 2, uncommon factors = 3 x 2 x 2 (12) and the LCD is 2 x 12 =24
By the exponential method
6 = 21 x 31
8 = 23
and 23 x 31 = 8 x 3 = 24
There is none because the Least Common Denominator (or LCD) refers to the Least Common Multiple (LCM) of the denominators of two or more fractions or mixed numbers. Even if you converted your whole numbers (x) to their fraction equivalents (x/1), the LCD would always be 1.

The least common denominator is the smallest whole number that can be divisible by two numbers. 4: 4, 8 8: 8 8 is the least common denominator for 4 and 8.
21/24 and 20/24
120
The least common denominator for 10, 8, and 7 is one. Since each whole number can be written as itself over one, these numbers already have the same denominator, which in turn is the LCD.
The Least Common Multiple (LCM) of 6 8 and 10 is 120.
