LCM of decimals calculator gives the LCM of Decimal numbers given 30, 24, 20 i.e. 120 the smallest number that divides all of them exactly.

Least Common Multiple (LCM) of 30, 24, 20 is 120.

LCM(30, 24, 20) = 120

LCM of 30, 24, 20

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 30, 24, 20

Given numbers are 30,24,20. 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

30 x 10 = 300

24 x 10 = 240

20 x 10 = 200

On finding the LCM of 300,240,200 we get the Least Common Multiple as 1200

Least Common Multiple 30,24,20 is 120

2 300, 240, 200
2 150, 120, 100
2 75, 60, 50
3 75, 30, 25
5 25, 10, 25
5 5, 2, 5
1, 2, 1

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 5 x 5 x 1 x 2 x 1 = 1200

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 1200/10 we get 120

Thus the Least Common Multiple of 30,24,20 is 120

Least Common Multiple of 300,240,200 with GCF Formula

Least Common Multiple of 300,240,200 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 300,240,200 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(300,240,200) = 20

common factors(in case of two or more numbers have common factors) = 600

GCF(300,240,200) x common factors =20 x 600 = 12000

LCM(300,240,200) = ( 300 × 240 × 200 ) / 12000

LCM(300,240,200) = 14400000 / 12000

LCM(300,240,200) = 1200
