About this tool
Enter two or more whole numbers separated by commas or spaces. You get the greatest common factor (also called HCF or GCD), the least common multiple and the prime factorisation of each number.
When to use it
Find the least common multiple and greatest common factor of numbers.
Tips
Use the LCM to add fractions and the GCF to simplify them.
Privacy
Everything runs in your browser, so your data is not uploaded or stored.
Methods
Find the GCF by listing common factors or dividing by common primes, and the LCM by taking each prime to its highest power. The product of two numbers equals their GCF times their LCM.
计算示例
With the boxes at their starting values (Numbers (separated by commas): 12, 18, 30), the tool shows: LCM (least common multiple): 180; 12: 2^2 × 3; 18: 2 × 3^2; 30: 2 × 3 × 5; GCF (greatest common factor): 6. Change any box to see your own numbers. The result updates as you type, and nothing leaves your browser.
