MATH CALCULATOR
Least Common Denominator Calculator
Find the least common denominator for fractions quickly and easily.
What is the Least Common Denominator Calculator & How does it work?
The least common denominator (LCD) is the smallest number that can be evenly divided by all denominators in a set of fractions. It is essential for adding or subtracting fractions with different denominators.
To find the LCD, you can use the prime factorization method. First, find the prime factors of each denominator. Then, take the highest power of each prime that appears in any of the factorizations and multiply them together to get the LCD.

text{LCD} = prod_{i=1}^{n} p_i^{e_i}
pi = prime factor, ei = highest power of the prime factor in any denominator
