LCM of decimals calculator gives the LCM of Decimal numbers given 1.2, 2, 2.8 i.e. 42 the smallest number that divides all of them exactly.

Least Common Multiple (LCM) of 1.2, 2, 2.8 is **42**.

LCM(1.2, 2, 2.8) = 42

Enter two or more decimals separated by "commas"

Ex: 0.2, 0.3 or 0.4, 0.5, 0.6

Given numbers are 1.2,2,2.8. The highest number of digits after the decimal point in the given case is 1

Thus, in order to get rid of the decimal point we need to multiply them with 10. On doing so, they are as follows

1.2 x 10 = 12

2 x 10 = 20

2.8 x 10 = 28

On finding the LCM of 12,20,28 we get the Least Common Multiple as 420

2 | 12, 20, 28 |

2 | 6, 10, 14 |

3, 5, 7 |

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 7 = 420

Divide the result you got with the number you multiplied to make it as integer in the first step. In this case, we need to divide by 10 as we used it to make the given numbers into integers.

On dividing the LCM 420/10 we get 42

Thus the Least Common Multiple of 1.2,2,2.8 is 42

The formula of **LCM** is LCM(a_{1},a_{2},a_{3}....,a_{n}) = ( a_{1} × a_{2} × a_{3} × .... × a_{n}) / GCF(a_{1},a_{2},a_{3}....,a_{n}) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 12,20,28 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(12,20,28) = 4

common factors(in case of two or more numbers have common factors) = 4

GCF(12,20,28) x common factors =4 x 4 = 16

LCM(12,20,28) = ( 12 × 20 × 28 ) / 16

LCM(12,20,28) = 6720 / 16

LCM(12,20,28) = 420

Here are some samples of LCM of Decimals calculations.

1. What is the LCM of 1.2, 2, 2.8?

Answer: LCM of 1.2, 2, 2.8 is 42.

2. How to Find the LCM of 1.2, 2, 2.8?

Answer: Least Common Factor(LCM) of 1.2, 2, 2.8 = 42

Step 1: First calculate the highest decimal number after decimal point.

Step 2: Then multiply all numbers with 10.

Step 3: Then find LCM of 12,20,28. After getting LCM devide the result with 10 the value that is previously multiplied.

So LCM(1.2, 2, 2.8) = 42.
