The lowest common denominator of any two positive numbers is always 1.

The common denominator of any two or more whole numbers will always be 1.

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 lowest common denominator of any two positive numbers is always 1.

A single number cannot have a lowest common denominator because "common" refers to multiples that two or more numbers have in common. You have only one number.

The lowest common denominator of any two or more whole numbers, such as 7 9 and 13, 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 LCM is 52

The lowest common denominator of any two or more whole numbers, such as 11 and 13, will always be one (1) because common denominators 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 common denominator is usually the Lowest (or Least) Common Multiple of the numbers involved. Where two numbers have no common factors then the LCM is simply the product of those numbers. As 19 is a prime number and has no factors in common with 18 then the common denominator is 18 x 19 = 342.

A single number cannot have anything in common. To find a lowest common denominator, you need to be adding or subtracting at least two fractions.

The common denominator of any two or more whole numbers will always be 1.

First, you have to have a lowest common denominator. Eg: 1/2 - 6/13 The lowest common denominator is 26, because 13 * 2 is 26. You multiply 1/2 by 13, to make the denominator 26, which equals 13/26, then multiply 6/13 by 2 to get 12/26. So the equation with the lowest common denominators now plugged in is: 13/26 - 12/26 Subtract the numerators (13 and 12), so the answer is 1/26.
