The common denominator of any two or more whole numbers, such as 5 6 and 8, 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.
24 and 48 are two possible common denominators for 3/8 and 5/6.
8/9, 5/12, 6/7
The Least Common Multiple (LCM) for 6 8 9 is 72.
To add fractions with the same denominators, simply add together the numerators, and cancel down if necessary. For example, 5/8 + 1/8 = 6/8. Cancelling this down to an improper fraction in its simplest form, this is equal to 3/4.
3 1 7 4 + 8 is 8. Remember to change the denominators into common denominators. (3/4 would turn into 6/8)
24 and 48 are two possible common denominators for 3/8 and 5/6.
8/9, 5/12, 6/7
The least common denominator for fractions with those denominators (11, 8 and 6) is 264.

The least common denominator is 144. Other common denominators would be multiples of 144. If that's 1/2, 1/6 and 1/8, the LCD is 24.
Least number is 120 if the three numbers are the denominators of fractions
Change them so they have like denominators. Multiply all that fractions by the least common denominator so that they'll have the same denominators. Example: 1/2 - 1/3 Step 1: The least common denominator is 6. Step 2: Change each fraction so their denominator is 6 (You'll get 3/6 and 2/6) Step 3: Subtract them: 3/6 - 2/6 = 1/6
The LCD is 40.
To add two fractions, you must first convert them to a common denominator, which is the Least Common Multiple of the denominators of the two fractions you're adding. For example, to add 5/6 and 1/8, you convert them to the common denominator LCM(6,8)=24. Then 5/6=20/24 and 1/8=3/24 so the sum is 23/24. To multiply two fractions, you multiply the numerators together and multiply the denominators together. Thus, 5/6 * 1/8 = (5*1)/(6*8) = 5/48. If both fractions are between 0 and 1, then the sum will always be greater than the product.
