Least Common Multiple of 4.5, 7.5, 9, 12.3

LCM of decimals calculator gives the LCM of Decimal numbers given 4.5, 7.5, 9, 12.3 i.e. 1845 the smallest number that divides all of them exactly.

Least Common Multiple (LCM) of 4.5, 7.5, 9, 12.3 is 1845.

LCM(4.5, 7.5, 9, 12.3) = 1845

LCM of 4.5, 7.5, 9, 12.3

Enter two or more decimals separated by "commas"

Ex: 0.2, 0.3 or 0.4, 0.5, 0.6

LCM of:

Given numbers are 4.5,7.5,9,12.3. 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

4.5 x 10 = 45

7.5 x 10 = 75

9 x 10 = 90

12.3 x 10 = 123

On finding the LCM of 45,75,90,123 we get the Least Common Multiple as 18450

Least Common Multiple (LCM) of 45,75,90,123 By Common Division

3 45, 75, 90, 123
3 15, 25, 30, 41
5 5, 25, 10, 41
1, 5, 2, 41

∴ So the LCM of the given numbers is 3 x 3 x 5 x 1 x 5 x 2 x 41 = 18450

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 18450/10 we get 1845

Thus the Least Common Multiple of 4.5,7.5,9,12.3 is 1845

Least Common Multiple of 45,75,90,123 with GCF Formula

Least Common Multiple of 45,75,90,123 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 45,75,90,123 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,75,90,123) = 3

common factors(in case of two or more numbers have common factors) = 675

GCF(45,75,90,123) x common factors =3 x 675 = 2025

LCM(45,75,90,123) = ( 45 × 75 × 90 × 123 ) / 2025

LCM(45,75,90,123) = 37361250 / 2025

LCM(45,75,90,123) = 18450
