Know Least Common Multiple of fractions 30/28, 21/41, 867/305 quickly i.e. 60690 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 30/28, 21/41, 867/305 is 60690.
LCM(30/28, 21/41, 867/305) = 60690
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 30/28,21/41,867/305
Formula to find LCM of Fractions is
LCM = LCM of Numerators/GCF of Denominators
As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators
In the given fractions LCM of Numerators means LCM of 30,21,867
Least Common Multiple of Numerators i.e. LCM of 30,21,867 is 60690.
GCF of Denominators means GCF of 28,41,305 as per the given fractions.
GCF of 28,41,305 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 30,21,867
3 | 30, 21, 867 |
10, 7, 289 |
∴ So the LCM of the given numbers is 3 x 10 x 7 x 289 = 60690
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 30,21,867 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,21,867) = 3
common factors(in case of two or more numbers have common factors) = 3
GCF(30,21,867) x common factors =3 x 3 = 9
LCM(30,21,867) = ( 30 × 21 × 867 ) / 9
LCM(30,21,867) = 546210 / 9
LCM(30,21,867) = 60690
Lets's calculate GCF of 28,41,305
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 60690/1
Therefore the LCM of Fractions 30/28,21/41,867/305 is 60690
