We can obtain common denominators by multiplying both numerator (top) and denominator (bottom) by the same amount. For example, consider the addition of two fractions that do not have the same denominator: Addition of 2 ⁄ 5 and 1 ⁄
To find the least common denominator first convert all integers and mixed numbers (mixed fractions) into fractions. Then find the lowest common multiple (LCM) of the denominators. This number is same as the least common
How To Find a Common Denominator? Definition, Examples
A problem of finding the common denominator of two or more fractions is the same as the problem of finding the least common multiple (LCM) of the denominators of these fractions. If the denominators of the given fractions are
Common Denominator
Calculate the least common multiple LCM (3; 7; 13) LCM (3; 7; 13) = 273. Find additional factors for each fraction, for this divide LCM by the denominators of each fraction: 273 : 3 = 91 (factor
