🔢 LCM and HCF Calculator – Simplify Numbers the Smart Way

The LCM and HCF Calculator by UnitXpert is a smart, easy-to-use online tool designed to instantly calculate the LCM (Least Common Multiple) and HCF (Highest Common Factor) of any two or more numbers. Whether you’re a student, teacher, parent, or just someone brushing up on math, this free tool helps you find the LCM HCF in seconds—without any manual effort or complex formulas.

✅ What Are LCM and HCF?

Let’s start with the basics. The LCM, or Least Common Multiple, is the smallest multiple that two or more numbers have in common. Meanwhile, the HCF, or Highest Common Factor (also known as GCD – Greatest Common Divisor), is the largest factor that divides those numbers exactly.

Knowing how to calculate LCM HCF is fundamental in arithmetic, algebra, and number theory. It is commonly used in problems involving fractions, ratios, time schedules, and number patterns.

⚡ How to Use the LCM and HCF Calculator?

Using this LCM and HCF Calculator is incredibly simple:

  1. Enter two or more numbers separated by commas (e.g., 12, 18, 24).
  2. Click the “Calculate” button.
  3. Instantly view the LCM and HCF results below.

The tool automatically removes invalid entries and calculates both values using the efficient Euclidean Algorithm behind the scenes.
