LCM of decimals calculator gives the LCM of Decimal numbers given 0.5, 0.4, 0.4, 0.398 i.e. 398 the smallest number that divides all of them exactly.
Least Common Multiple (LCM) of 0.5, 0.4, 0.4, 0.398 is 398.
LCM(0.5, 0.4, 0.4, 0.398) = 398
LCM of 0.5, 0.4, 0.4, 0.398
Enter two or more decimals separated by "commas"
Ex: 0.2, 0.3 or 0.4, 0.5, 0.6
Given numbers are 0.5,0.4,0.4,0.398. 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
0.5 x 1000 = 500
0.4 x 1000 = 400
0.4 x 1000 = 400
0.398 x 1000 = 398
On finding the LCM of 500,400,400,398 we get the Least Common Multiple as 398000
Least Common Multiple 0.5,0.4,0.4,0.398 is 398
| 2 | 500, 400, 400, 398 |
| 2 | 250, 200, 200, 199 |
| 2 | 125, 100, 100, 199 |
| 2 | 125, 50, 50, 199 |
| 5 | 125, 25, 25, 199 |
| 5 | 5, 5, 25, 199 |
| 1, 1, 5, 199 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 5 x 1 x 1 x 5 x 199 = 398000
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 398000/1000 we get 398
Thus the Least Common Multiple of 0.5,0.4,0.4,0.398 is 398
Least Common Multiple of 500,400,400,398 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 500,400,400,398 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(500,400,400,398) = 2
common factors(in case of two or more numbers have common factors) = 40000
GCF(500,400,400,398) x common factors =2 x 40000 = 80000
LCM(500,400,400,398) = ( 500 × 400 × 400 × 398 ) / 80000
LCM(500,400,400,398) = 31840000000 / 80000
LCM(500,400,400,398) = 398000
