Multiplying the denominators together of two or more unlike fractions will get you a common multiple.

The least common denominator of two fractions is the least common multiple of the two denominators.

The least common denominator is the least common multiple of the denominators of the fractions.

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.

Common denominators are common multiples of two or more denominators.

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator.

a common denominator

Common denominators are common multiples that are being used as denominators.

The LCD for fractions is the LCM (least common multiple) of all of the denominators.

It is the LCD.

the common denominator!

You convert them to equivalent fractions each of whose denominators are the same - either the lowest common multiple (LCM) of the original denominators or a multiple of the LCM.

Probably the most common use is in adding fractions with different denominators. The least common multiple of the denominators is the least common denominator. Each fraction can be converted to one with the common denominator, and then you can add the fractions by adding their numerators.

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

In fractions, the denominator is the bottom number. When adding or subtracting fractions, it is helpful if all the denominators are the same. To do this, we look for common denominators, which is the same process as finding the least common multiple.

They are essentially the same. A common denominator is the common multiple of a set of denominators of a set of fractions.

Find the lowest common multiple of the denominators and adjust the fractions accordingly

No. To multiple fractions multiple the numerators together and multiply the denominators together and simplify (by dividing both numerator and denominator of the result by common factors until the only common factor is 1). The denominators only need to be the same when adding or subtracting fractions.
