Calculating the GCF (Greatest Common Factor) and LCM (Least Common Multiple)
processes can be tedious sometimes. With this free, online calculator we developed, you can instantly and flawlessly find both the greatest common factor (GCF, or EBOB in Turkish) and the least common multiple (LCM, or EKOK in Turkish) of two numbers.
In What Situations Is It Used?
This handy
GCF LCM calculator tool
saves you time while solving mathematical problems. The most common use cases include:
Education and Homework:
Middle school, high school, and test-prep students checking their math homework.
Simplifying Fractions:
Calculating the GCF of the numerator and denominator to find the simplest form of complex and large-valued fractions.
Equating Denominators:
Swiftly finding the common denominator (LCM) when adding or subtracting rational numbers.
Scheduling and Shift Problems:
Using the LCM to solve problems that follow ratio-proportion logic, such as determining when two people who work shifts every 4 days and 6 days respectively will work a shift together again.
Operation Examples (Current 2026)
You can better understand how the system works through these example calculation operations:
Example 1: Finding the GCF
Let's consider the divisors of the numbers 12 and 18. The numbers that divide both are: 1, 2, 3, and 6. In this case, the Greatest Common Factor (GCF) emerges as 6.
Example 2: Finding the LCM
When analyzing the common multiples of 20 and 30, they are: 60, 120, 180... Therefore, the lowest common multiple among them (LCM) is 60. Using our tool, you can solve these with a single click online instead of manually doing the math.

Frequently Asked Questions
Yes, the GCF LCM calculation tool on ToolboxTR is completely free. You can use it online 24/7 without requiring any membership.
GCF (Greatest Common Factor) is usually found by the Euclidean Algorithm or the prime factorization method. Our tool uses modern algorithms to give the most accurate result in seconds.
The product of two numbers is always equal to the product of the GCF and LCM values of those two numbers (a × b = GCF × LCM). This formula is frequently useful in mathematical verifications.
Mathematically, it is possible to work with negative numbers, but GCF and LCM are always expressed as positive integers. Our tool works with the absolute value principle to provide error-free results.
