LCM of decimals calculator gives the LCM of Decimal numbers given 10.8, 18, 28.8 i.e. 432 the smallest number that divides all of them exactly.
Least Common Multiple (LCM) of 10.8, 18, 28.8 is 432.
LCM(10.8, 18, 28.8) = 432
Enter two or more decimals separated by "commas"
Ex: 0.2, 0.3 or 0.4, 0.5, 0.6
Given numbers are 10.8,18,28.8. 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
10.8 x 10 = 108
18 x 10 = 180
28.8 x 10 = 288
On finding the LCM of 108,180,288 we get the Least Common Multiple as 4320
2 | 108, 180, 288 |
2 | 54, 90, 144 |
3 | 27, 45, 72 |
3 | 9, 15, 24 |
3, 5, 8 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 3 x 5 x 8 = 4320
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 4320/10 we get 432
Thus the Least Common Multiple of 10.8,18,28.8 is 432
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 108,180,288 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(108,180,288) = 36
common factors(in case of two or more numbers have common factors) = 36
GCF(108,180,288) x common factors =36 x 36 = 1296
LCM(108,180,288) = ( 108 × 180 × 288 ) / 1296
LCM(108,180,288) = 5598720 / 1296
LCM(108,180,288) = 4320
Here are some samples of LCM of Decimals calculations.
1. What is the LCM of 10.8, 18, 28.8?
Answer: LCM of 10.8, 18, 28.8 is 432.
2. How to Find the LCM of 10.8, 18, 28.8?
Answer: Least Common Factor(LCM) of 10.8, 18, 28.8 = 432
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 108,180,288. After getting LCM devide the result with 10 the value that is previously multiplied.
So LCM(10.8, 18, 28.8) = 432.
