Least Common Denominator
Use this calculator to find the least common denominator of a list of fractions. Use spaces to separate the fractions.
How to rewrite multiple fractions with the same denominator
- If necessary, simplify the fractions (more details on Simplify a fraction.)
- Calculate the LCM (Least Common Multiple) of the denominators (more details on the LCM)
Example: Find common denominators of fractions `3/5`, `3/10`, and `1/2`
Fractions are irreducible, we proceed as follows,
LCM (5,10,2) = 10
Fractions are equal to,
`(3*2)/(5*2)`, `(3*1)/(10*1)` and `(1*5)/(2*5)`
Therefore,
`6/10`, `3/10` and `5/10`
