Know Least Common Multiple of fractions 666/382, 2571/6440 quickly i.e. 285381 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 666/382, 2571/6440 is 285381.
LCM(666/382, 2571/6440) = 285381
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 666/382,2571/6440
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 666,2571
Least Common Multiple of Numerators i.e. LCM of 666,2571 is 570762.
GCF of Denominators means GCF of 382,6440 as per the given fractions.
GCF of 382,6440 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 666,2571
3 | 666, 2571 |
222, 857 |
∴ So the LCM of the given numbers is 3 x 222 x 857 = 570762
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 666,2571 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(666,2571) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(666,2571) x common factors =3 x 1 = 3
LCM(666,2571) = ( 666 × 2571 ) / 3
LCM(666,2571) = 1712286 / 3
LCM(666,2571) = 570762
Lets's calculate GCF of 382,6440
2 | 382, 6440 |
191, 3220 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 570762/2
Therefore the LCM of Fractions 666/382,2571/6440 is 285381
