LCM Calculator and HCF Calculator

About our LCM calculator and HCF calculator

LCM calculator and HCF calculator are the two most important calculators are provided here.  

How to use our calculator:

  • Enter only cthe whole numbers for which you want to calculate LCM and HCF.
  • Do not use separators like comma. (Ex: 1,525 to be typed as 1525)
  • Do not use decimals.

                              First Number:

                          Second Number:

          Third Number (If required):

        Highest Common Factor (HCF):

      Least Common Multiplier (LCM):

How to use our calculator for decimals:

Example: Find the HCF and LCM of 06, 9.6, 0.12. 


In all the given three numbers, we have decimals. In this case, first we have to find, where we have more number of digits after the decimal. Clearly we have two digits after the decimal in the number 0.12.

So, we have to multiply each of the given numbers by 100. (for three digits, multiply by 1000)

0.6x100 = 60

9.6x100 = 960

0.12 x 100 = 12

After having multiplied by 100, we get 60, 960, 12.

Now, find the HCF and LCM of 60, 960, 12 using the calculator. 

HCF of 60, 960, 12 = 12

LCM of 60, 960, 12 = 960

From this, we can get HCF and LCM of 0.6, 9.6, 0.12 by dividing the above result by 100. (Because, we have multiplied by 100 earlier)

HCF of 0.6, 9.6, 0.12 = 0.12

LCM of 0.6, 9.6, 0.12 = 9.6

Why do people need LCM and HCF calculator?

Apart from the regular calculator, people who study math are in need of LCM and HCF calculator. Because, when people work out lengthy problems, they may not have time to find LCM and HCF of some numbers. At that time, calculating LCM and HCF would be an additional burden for them in solving lengthy math problems. To reduce the burden of those people, we have provided online LCM calculator and HCF calculator.

Using the calculator in solving word problems

When people do preparation of solving word problems on HCF and LCM, they may have to spend time to get idea on "How to solve". In this situation, they would not like to spend time to do calculation of LCM and HCF manually. And also they would not be able to use the regular calculators to calculate LCM and HCF. By using this calculator, students will find much time to get idea of solving the word problems.
