The lowest common denominator of any two or more whole numbers, such as 15 and 21, 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.

What is the lowest common multiple for 15 and 21?
7
What is 2.21 as a mixed number?
2 21/100 Since 21 can be divided by 3 and 7 (lowest primes), but 100 cannot, then logically, 100 is the lowest common denominator for this, therefore 21/100
What is the lowest common denominator of 9 and 11 14 21?
The lowest common denominator of any two or more whole numbers, such as 9 11 14 and 21, 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.
