Know Least Common Multiple of fractions 64/191, 490/82, 840/855 quickly i.e. 47040 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 64/191, 490/82, 840/855 is 47040.
LCM(64/191, 490/82, 840/855) = 47040
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 64/191,490/82,840/855
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 64,490,840
Least Common Multiple of Numerators i.e. LCM of 64,490,840 is 47040.
GCF of Denominators means GCF of 191,82,855 as per the given fractions.
GCF of 191,82,855 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 64,490,840
2 | 64, 490, 840 |
2 | 32, 245, 420 |
2 | 16, 245, 210 |
5 | 8, 245, 105 |
7 | 8, 49, 21 |
8, 7, 3 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 7 x 8 x 7 x 3 = 47040
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 64,490,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(64,490,840) = 2
common factors(in case of two or more numbers have common factors) = 280
GCF(64,490,840) x common factors =2 x 280 = 560
LCM(64,490,840) = ( 64 × 490 × 840 ) / 560
LCM(64,490,840) = 26342400 / 560
LCM(64,490,840) = 47040
Lets's calculate GCF of 191,82,855
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 47040/1
Therefore the LCM of Fractions 64/191,490/82,840/855 is 47040
