The common denominator of any two or more whole numbers, such as 16 and 7, 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.
16 is the answer you're looking for. If you have two fractions with denominators of 8 & 16, then 16 is the Least Common Multiple of the two denominators.
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.

The Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions. I assume the 7 and 21 are the denominators of two fractions you need to add or subtract.LCD(7, 21) = 21.
Since these fractions have common denominators we can simply add the numerators, keep the denominators the same, and reduce (simplify).Add:27/16 + 19/16 = 46/16Reduce:46 ÷ 16 = 22 x 16 = 3246 - 32 = 1414/16 = 14 ÷ 2 / 16 ÷ 2Rewrite:14/16 = 7/827/16 + 19/16 = 46/16 = 2 7/8So, 27/16 + 19/16 = 2 7/8 (Two and Seven-Eighths).
Only 1.
The least common denominator of 9, 12, and 16 is 144.
Common multiples and common denominators can be found using the same process. They differ in their function. Common denominators are common multiples that are functioning as denominators.
7/8 + 5/16 to add fractions you need common denominators and 16 will do here, using This (2/2) form of one to convert the fraction needed 2*7/2*8 + 5/16 14/16 + 5/16 = 19/16 ----------------simplest form
If you get the denominators to a common factor, the fractions 3/16 and 7/31 are equivalent to 93/496 and 112/496. From this, it is easier to see that 112/496 is larger. So, 7/31 is greater than 3/16.
