The common denominator of any two or more whole numbers, such as 4 18 and 19, 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.

What is the least common denominator of 18 4 and 20?
LCD(18, 4, 20) = 180
What is the least common denominator of 1 over 4 and 19 over 20?
20 is.
What is the common denominator of 19?
a common denominator is a number that 2 numbers can be divided by evenly, 8 and 12 are both divisible by 4 and 2 and 1, so those are their common denominators. Normally you would need 2 numbers to get a common denominator, but because 19 is a prime number, (which means it can only be divided by 1 and itself 19) then no matter what other number is paired with it, there will only be 1 common denominator and that is 1
What is the least common denominator of 4 over 9 and 5 over 6?
LCD(9, 6) = 18
Is 5 out of 6 greater than 19 out of 24?
Yes, 5 out of 6 is greater than 19 out of 24. Both fractions can be simplified to 5/6 and 19/24 respectively. When comparing fractions, it is helpful to have a common denominator. In this case, the common denominator is 24. When the fractions are written with this common denominator, it is clear that 5/6 is larger than 19/24.
