The easiest way is to multiply the different denominators together. If you prefer to work with smaller denominators, several methods exist:
1) For small numbers, check different multiples of the largest denominator, until you get one that is a multiple of the other one.
2) Do prime factoring, and then multiply together all prime numbers that appear at least in one of the denominators.
3) Factoring can be complicated for large numbers; euclids algorithm is much more efficient in this case.
What else can I help you with?
What is the common denominator of fraction 4 5th?
You need at least two fractions to calculate a common denominator.
What are fractions that have the same denominator called?
Like Fractions
How do you calculate the sum of fractions?
If the fractions do not all have the same denominator, find a common multiple of the denominators (ideally the lowest common multiple) and convert the fractions to equivalent fractions with this denominator. Now with all the fractions with the same denominator, add together the numerators. Finally, reduce the fraction to simplest terms, converting any improper fraction to a mixed number.
What are like and unlike fractions?
Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.
How do you minnous fractions?
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

How do you calculate equivalent fractions?
Multiply the numerator and the denominator of the fraction by the same, non-zero integer.
What are regular fractions?
Regular fractions are the fractions with a numerator that is less than the denominator and irregular fractions are fractions with a denominator less than the numerator.
How do you calculate fractions?
Divide the numerator by the denominator. For example, 3/4 = 3 divided by four =.75
Why do you have to find a common denominator?
Addition or subtraction of fractions require "like" fractions: that is, fractions with the same denominator.
What is similar fraction?
Similiar fractions are fractions that have the same denominator.
How do you subtract fractions when denominator is different?
By finding the lowest common denominator of the fractions.
What are the types of fractions?
The two types of fractions are proper fractions, in which the numerator is smaller than the denominator, and improper fractions, in which the numerator is equal to or larger than the denominator.
