# HCF AND LCM CALCULATOR

The calculator given in this section can be used to find HCF and LCM for the given data values.

How to use this calculator :

• Enter only the 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 this calculator for decimals:

Example:

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

Solution:

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)

0.6 ⋅ 100  =  60

9.6 ⋅ 100  =  960

0.12  100  =  12

After having multiplied by 100, we get 60, 960 and 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
