It's the same process as finding least common multiples.
Example: 1/30 and 1/42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Combine the factors, eliminating duplicates.
2 x 3 x 5 x 7 = 210, the LCD
The common denominator for a set of numbers is identified by simply multiplying the numbers together. This will not be the least common denominator, but that is not what the question is about.
the least denominator is the bottom number of a fraction that u use the least
If you mean the steps, they are as follows:* Identify a common denominator. Any common denominator will do. * Convert both fractions to equivalent fractions, with the common denominator found in the previous step. (If the fractions start off with the same denominator, there is nothing else to do in these first two steps.) * Add the numerators. That's the numerator of the result. Copy the common denominator as the denominator of the result. * Check whether you can simplify the resulting fraction.
A few synonyms for common denominator are , common divisor, common measure, denominator, numerator
The Least Common Multiple of 3 and 5 is 15, which would be the denominator to use for fractions with the denominators 3 and 5.
The common denominator for a set of numbers is identified by simply multiplying the numbers together. This will not be the least common denominator, but that is not what the question is about.
For the sake of comparison, any common denominator will do.

Just add the fractions, and divide by 2. Before adding, you have to convert to a common denominator; in this case, you can use "4" as the common denominator.Just add the fractions, and divide by 2.

yes you should use a common denominator when subtracting with fractions, it makes it much easier.
That's the least common denominator or LCD.
The least common denominator.
Just use the GCF(greatest common factor

The least common denominator refers to integers, not decimals. If you convert that 8.5 to 17ths, you could use 476ths.
