LCM of decimals calculator gives the LCM of Decimal numbers given 15, 18.75 i.e. 75 the smallest number that divides all of them exactly.
Least Common Multiple (LCM) of 15, 18.75 is 75.
LCM(15, 18.75) = 75
LCM of 15, 18.75
Enter two or more decimals separated by "commas"
Ex: 0.2, 0.3 or 0.4, 0.5, 0.6
Given numbers are 15,18.75. The highest number of digits after the decimal point in the given case is 2
Thus, in order to get rid of the decimal point we need to multiply them with 100. On doing so, they are as follows
15 x 100 = 1500
18.75 x 100 = 1875
On finding the LCM of 1500,1875 we get the Least Common Multiple as 7500
Least Common Multiple 15,18.75 is 75
| 3 | 1500, 1875 |
| 5 | 500, 625 |
| 5 | 100, 125 |
| 5 | 20, 25 |
| 4, 5 |
∴ So the LCM of the given numbers is 3 x 5 x 5 x 5 x 4 x 5 = 7500
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 100 as we used it to make the given numbers into integers.
On dividing the LCM 7500/100 we get 75
Thus the Least Common Multiple of 15,18.75 is 75
Least Common Multiple of 1500,1875 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 1500,1875 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(1500,1875) = 375
common factors(in case of two or more numbers have common factors) = 1
GCF(1500,1875) x common factors =375 x 1 = 375
LCM(1500,1875) = ( 1500 × 1875 ) / 375
LCM(1500,1875) = 2812500 / 375
LCM(1500,1875) = 7500
