There is none because 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 fraction is not reduced to lowest terms. We can reduce this fraction to lowest terms by dividing both the numerator and denominator by 4, because 4 is the Greatest Common Divisor of the numbers 52 and 64. So, this fraction reduced to lowest terms is 13/16
52/64 = 13/16
The greatest common denominator is infinite.
The greatest common factor of 52 and 64 is 4.
You can have a least common denominator or a greatest common factor but a greatest common denominator does not exist.
The LCD of 36 and 64 is 576
The LCM is: 64
The greatest common denominator of any set of denominators is infinite.
The least common denominator between fractions 1 over 32 and 8 over 64 is 64.
At least one other fraction is needed to determine a common denominator.
The greatest common denominator is infinite. The least is 192. The greatest common factor is 16.
The GCF is 4.
