LCM of decimals calculator gives the LCM of Decimal numbers given 10.5, 12.8, 18 i.e. 4032 the smallest number that divides all of them exactly.

Least Common Multiple (LCM) of 10.5, 12.8, 18 is 4032.

LCM(10.5, 12.8, 18) = 4032

LCM of 10.5, 12.8, 18

Enter two or more decimals separated by "commas"

Ex: 0.2, 0.3 or 0.4, 0.5, 0.6

LCM of:

Least Common Multiple of 10.5, 12.8, 18

Given numbers are 10.5,12.8,18. 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

10.5 x 10 = 105

12.8 x 10 = 128

18 x 10 = 180

On finding the LCM of 105,128,180 we get the Least Common Multiple as 40320

Least Common Multiple 10.5,12.8,18 is 4032

2 105, 128, 180
2 105, 64, 90
3 105, 32, 45
5 35, 32, 15
7, 32, 3

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 7 x 32 x 3 = 40320

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 40320/10 we get 4032

Thus the Least Common Multiple of 10.5,12.8,18 is 4032

Least Common Multiple of 105,128,180 with GCF Formula

Least Common Multiple of 105,128,180 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 105,128,180 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(105,128,180) = 1

common factors(in case of two or more numbers have common factors) = 60

GCF(105,128,180) x common factors =1 x 60 = 60

LCM(105,128,180) = ( 105 × 128 × 180 ) / 60

LCM(105,128,180) = 2419200 / 60

LCM(105,128,180) = 40320
