The lowest common denominator of any two or more whole numbers, such as 11 and 20, will always be one (1) because 'common denominator' refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.
The denominators of 20 and 15 are both 1, therefore, the lowest common denominator is 1.
The answer is 20.
The lowest common denominator of any set of whole numbers is 1
The lowest common denominator of any two positive numbers is always 1.

20 is the lowest common denominator for 4 and 10.

LCD(4, 5) = 20.

The lowest common denominator or least common multiple of 7 and 20 is 140.

11 over 24 (11/24) Here's how: You need to find a common denominator. The lowest common denominator is 24, but you can use any common denominator to subtract. So convert 5/6 to 24ths: multiply numerator and denominator by 4 = 20/24, then multiply numerator and denominator of 3/8 by 3 = 9/24. Now subtract 9 from 20 = 11, which is the numerator of the difference: 11/24. This is already in simplest form.
