LCM of decimals calculator gives the LCM of Decimal numbers given 0.1, 0.2, 0.9, 0.645 i.e. 77.4 the smallest number that divides all of them exactly.
Least Common Multiple (LCM) of 0.1, 0.2, 0.9, 0.645 is 77.4.
LCM(0.1, 0.2, 0.9, 0.645) = 77.4
LCM of 0.1, 0.2, 0.9, 0.645
Enter two or more decimals separated by "commas"
Ex: 0.2, 0.3 or 0.4, 0.5, 0.6
Given numbers are 0.1,0.2,0.9,0.645. 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
0.2 x 1000 = 200
0.9 x 1000 = 900
0.645 x 1000 = 645
On finding the LCM of 100,200,900,645 we get the Least Common Multiple as 77400
Least Common Multiple 0.1,0.2,0.9,0.645 is 77.4
| 2 | 100, 200, 900, 645 |
| 2 | 50, 100, 450, 645 |
| 3 | 25, 50, 225, 645 |
| 5 | 25, 50, 75, 215 |
| 5 | 5, 10, 15, 43 |
| 1, 2, 3, 43 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 5 x 1 x 2 x 3 x 43 = 77400
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 77400/1000 we get 77.4
Thus the Least Common Multiple of 0.1,0.2,0.9,0.645 is 77.4
Least Common Multiple of 100,200,900,645 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 100,200,900,645 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(100,200,900,645) = 5
common factors(in case of two or more numbers have common factors) = 30000
GCF(100,200,900,645) x common factors =5 x 30000 = 150000
LCM(100,200,900,645) = ( 100 × 200 × 900 × 645 ) / 150000
LCM(100,200,900,645) = 11610000000 / 150000
LCM(100,200,900,645) = 77400
