LCM of decimals calculator gives the LCM of Decimal numbers given 22.5, 15 i.e. 45 the smallest number that divides all of them exactly.
Least Common Multiple (LCM) of 22.5, 15 is 45.
LCM(22.5, 15) = 45
Enter two or more decimals separated by "commas"
Ex: 0.2, 0.3 or 0.4, 0.5, 0.6
Given numbers are 22.5,15. 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
22.5 x 10 = 225
15 x 10 = 150
On finding the LCM of 225,150 we get the Least Common Multiple as 450
3 | 225, 150 |
5 | 75, 50 |
5 | 15, 10 |
3, 2 |
∴ So the LCM of the given numbers is 3 x 5 x 5 x 3 x 2 = 450
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 450/10 we get 45
Thus the Least Common Multiple of 22.5,15 is 45
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 225,150 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(225,150) = 75
common factors(in case of two or more numbers have common factors) = 1
GCF(225,150) x common factors =75 x 1 = 75
LCM(225,150) = ( 225 × 150 ) / 75
LCM(225,150) = 33750 / 75
LCM(225,150) = 450
Here are some samples of LCM of Decimals calculations.
1. What is the LCM of 22.5, 15?
Answer: LCM of 22.5, 15 is 45.
2. How to Find the LCM of 22.5, 15?
Answer: Least Common Factor(LCM) of 22.5, 15 = 45
Step 1: First calculate the highest decimal number after decimal point.
Step 2: Then multiply all numbers with 10.
Step 3: Then find LCM of 225,150. After getting LCM devide the result with 10 the value that is previously multiplied.
So LCM(22.5, 15) = 45.
