# Adding Three Fractions with Different Denominators

Adding three fractions with different denominators involves a few steps. Foremost thing is to turn the unlike into like denominators by taking LCM of denominators. For example, LCM of denominators 4,6,8 would be 24. Hence 24 will be a common denominator. Here is the online Add 3 Unlike Fractions Calculator for adding three fractions with different denominators. Enter the values for three unlike fractions and click calculate to find the resultant value.

Code to add this calci to your website  #### Formula:

lcm = LCM (b1,b2,b3) Sum of Unlike denominators = (a1*(lcm/b1) + a2*(lcm/b2) + a3*(lcm/b3)) / lcm Where, a1, a2, a3 = Numerators b1, b2, b3 = Denominators LCM = Least Common Multiple

### Example:

Add three fractions with different denominators for the values a1 as 5, a2 as 4, a3 as 3, b1 as 7, b2 as 8 and b3 as 6.

#### Solution:

lcm = LCM (b1,b2,b3)
Sum of Unlike denominators = (a1*(lcm/b1) + a2*(lcm/b2) + a3*(lcm/b3)) / lcm
= 288 / 168
= 1.7143
