LCM of decimals calculator gives the LCM of Decimal numbers given 0.1, 0.3, 0.9, 0.405 i.e. 8.1 the smallest number that divides all of them exactly.
Least Common Multiple (LCM) of 0.1, 0.3, 0.9, 0.405 is 8.1.
LCM(0.1, 0.3, 0.9, 0.405) = 8.1
LCM of 0.1, 0.3, 0.9, 0.405
Enter two or more decimals separated by "commas"
Ex: 0.2, 0.3 or 0.4, 0.5, 0.6
Given numbers are 0.1,0.3,0.9,0.405. The highest number of digits after the decimal point in the given case is 3
Thus, in order to get rid of the decimal point we need to multiply them with 1000. On doing so, they are as follows
0.1 x 1000 = 100
0.3 x 1000 = 300
0.9 x 1000 = 900
0.405 x 1000 = 405
On finding the LCM of 100,300,900,405 we get the Least Common Multiple as 8100
Least Common Multiple 0.1,0.3,0.9,0.405 is 8.1
| 2 | 100, 300, 900, 405 |
| 2 | 50, 150, 450, 405 |
| 3 | 25, 75, 225, 405 |
| 3 | 25, 25, 75, 135 |
| 5 | 25, 25, 25, 45 |
| 5 | 5, 5, 5, 9 |
| 1, 1, 1, 9 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 5 x 5 x 1 x 1 x 1 x 9 = 8100
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 1000 as we used it to make the given numbers into integers.
On dividing the LCM 8100/1000 we get 8.1
Thus the Least Common Multiple of 0.1,0.3,0.9,0.405 is 8.1
Least Common Multiple of 100,300,900,405 with GCF Formula
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 100,300,900,405 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(100,300,900,405) = 5
common factors(in case of two or more numbers have common factors) = 270000
GCF(100,300,900,405) x common factors =5 x 270000 = 1350000
LCM(100,300,900,405) = ( 100 × 300 × 900 × 405 ) / 1350000
LCM(100,300,900,405) = 10935000000 / 1350000
LCM(100,300,900,405) = 8100
