The lowest common denominator of any set of whole numbers is 1
The least common denominator of a set of numbers is basically the least common multiple of a set of numbers.Therefore, with 9 and 3, the LCM/ LCD is 9 because 9 is the 3rd multiple of 3.
You need at least two fractions to find a common denominator.
for three 3 6 9 12 for five 5 10 15 20 these both numbers dont share a common denominator in the first 4 multiples
The bottom number of a fraction is called the denominator. In order to add and subtract fractions with different denominators, it is necessary to make them the same, or "common." Example: 1/4 + 1/5. The common denominator is 20. 1/4 = 5/20 1/5 = 4/20 1/4 + 1/5 = 5/20 + 4/20 = 9/20
