How to Find LCM of 12.5,18,30?
Given Numbers are 12.5,18,30
Given numbers are 12.5,18,30. 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
12.5 x 10 = 125
18 x 10 = 180
30 x 10 = 300
The LCM of 125,180,300 is 4500
So, the LCM of 12.5,18,30 is 450
| 2 | 125, 180, 300 |
| 2 | 125, 90, 150 |
| 3 | 125, 45, 75 |
| 5 | 125, 15, 25 |
| 5 | 5, 3, 25 |
| 1, 3, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 5 x 1 x 3 x 5 = 4500
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 4500/10 we get 450
Thus the Least Common Multiple of 12.5,18,30 is 450
Least Common Multiple of 125,180,300 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 125,180,300 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(125,180,300) = 5
common factors(in case of two or more numbers have common factors) = 300
GCF(125,180,300) x common factors =5 x 300 = 1500
LCM(125,180,300) = ( 125 × 180 × 300 ) / 1500
LCM(125,180,300) = 6750000 / 1500
LCM(125,180,300) = 4500
