Know Least Common Multiple of fractions 885/21, 7872/875 quickly i.e. 2322240/7 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 885/21, 7872/875 is 2322240/7.
LCM(885/21, 7872/875) = 2322240/7
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 885/21,7872/875
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 885,7872
Least Common Multiple of Numerators i.e. LCM of 885,7872 is 2322240.
GCF of Denominators means GCF of 21,875 as per the given fractions.
GCF of 21,875 is 7 as it is the largest common factor for these numbers.
Lets's calculate LCM of 885,7872
3 | 885, 7872 |
295, 2624 |
∴ So the LCM of the given numbers is 3 x 295 x 2624 = 2322240
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 885,7872 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(885,7872) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(885,7872) x common factors =3 x 1 = 3
LCM(885,7872) = ( 885 × 7872 ) / 3
LCM(885,7872) = 6966720 / 3
LCM(885,7872) = 2322240
Lets's calculate GCF of 21,875
7 | 21, 875 |
3, 125 |
∴ So the GCF of the given numbers is 7 = 7
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2322240/7
Therefore the LCM of Fractions 885/21,7872/875 is 2322240/7
