Identify the least common denominator by finding the least common multiple for the denominators.. 2. Now we need to multiply fractions, numerator and denominator, in such a way that the denominators of both fractions become equal to the LCM value. However, sometimes the denominators are different. Then, divide the least common multiple by the denominator in each fraction. Similarly, when we add fractions with different denominators we have to convert them to equivalent fractions with a common denominator. Take the number you get for each fraction and multiply it by the numerator and denominator of that fraction, which will make both denominators equal to the least common multiple.
