LCM of Decimal Numbers

In mathematics, the value that is equally divided by the two supplied numbers is known as the LCM of any two. Their least common multiple is the smallest among the common multiples of two or more numbers. Another name for it is the Least Common Divisor (LCD).

The accepted method for representing both integer and non-integer numbers is the decimal numeral system. The base-10 number system, arguably the most widely used number system, is referred to as decimal. It serves as the accepted method of designating both integer and non-integer numbers.

How to Calculate LCM of Decimal Numbers

  1. Check the given decimal numbers to find the LCM.
  2. Check & convert the decimal numbers accordingly to the integers by multiplying by the multiples of 10, 100 or a bigger number.
  3. Check the numbers after the multiplication & take their LCM.
  4. Check the answer & divide that answer by the same multiple used in step 2.
  5. Check the final answer as the LCM of given decimal numbers.

Solved Example with Easy Way to Calculate LCM


Calculate the LCM of decimal numbers 0.24 & 0.45.


Here, the decimal numbers are 0.24 & 0.45.

Let us multiply the given numbers by 100 to convert the given decimal numbers into integers.

Now, we get a new set of numbers as 24 & 45.

To calculate the LCM of the above numbers, let us factorize the numbers.

Here, 24 = 2 x 2 x 2 x 3

& 45 = 3 x 3 x 5

Now, LCM (24, 45) = 2 x 2 x 2 x 3 x 3 x 5 = 360

Now, by dividing the LCM (24, 45) by a factor of 100, we get 3.6.

So, we can say that the LCM of decimal numbers 0.24 & 0.45 is 3.6.
