It's the same process as finding the least common multiple.
Example: 7/30 + 13/42
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 LCM
Since 210 is the lowest common denominator, we can proceed to add them.
7/30 = 49/210
13/42 = 65/210
7/30 + 13/42 = 114/210 or 19/35 in lowest terms.

How do you add fractions without the same denominatior?
Find their least common denominator and convert them.
How do you find fractions from least to greatest?
you have to compare the common fractions
How do you find an equivalent fraction for a fraction by using the least common denominator?
you find the highest number that goes into both the numerator and the denominatior and divide both by that number.
How do you find the least common factor on fractions?
The least common factor of any set of integers is 1.
Is it always necessary to find the least common denominator to compare the sizes of fractions?
When comparing fractions you must find a common denominator; by finding the least common denominator it will keep the numbers (numerators and denominator) smaller .
Find the least common denominator for fractions with denominators 9 12 and 16?
The least common denominator is 144.
How do you find the least common denominator of a set of unlike fractions?
To find the least common denominator of a set of unlike fractions, you first need to list the prime factors of each denominator. Then, identify the highest power of each prime factor that appears in any of the denominators. Finally, multiply these highest powers together to find the least common multiple, which will be the least common denominator for the fractions.
How do you find the common denominator of 3 fractions?
Pick two of the fractions and find the Least Common Multiple of those two denominators. Then take that number, and find the Least Common Multiple between that and the third denominator. This number will be the Least Common Denominator between the three fractions.If you don't care to find the Least common denominator, then just take the three denominators, and multiply them together.
How do you order 2 or more fractions from least to greatest?
you can find the least common denominator and then order them.
What is the relationship between least common multiple and greatest common faction?
Least common multiple is needed to find the least common denominator when adding or subtracting fractions with different denominators Greatest common factor is needed when reducing fractions to their lowest terms
Find the least common denominator for fractions with denominators 45 and 42?
630
How you use the least common multiple?
When adding or subtracting unlike fractions, the LCM process is used to find the least common denominator.
