Know Least Common Multiple of fractions 5128/428, 1388/9894 quickly i.e. 889708 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 5128/428, 1388/9894 is 889708.
LCM(5128/428, 1388/9894) = 889708
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 5128/428,1388/9894
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 5128,1388
Least Common Multiple of Numerators i.e. LCM of 5128,1388 is 1779416.
GCF of Denominators means GCF of 428,9894 as per the given fractions.
GCF of 428,9894 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 5128,1388
2 | 5128, 1388 |
2 | 2564, 694 |
1282, 347 |
∴ So the LCM of the given numbers is 2 x 2 x 1282 x 347 = 1779416
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 5128,1388 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(5128,1388) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(5128,1388) x common factors =4 x 1 = 4
LCM(5128,1388) = ( 5128 × 1388 ) / 4
LCM(5128,1388) = 7117664 / 4
LCM(5128,1388) = 1779416
Lets's calculate GCF of 428,9894
2 | 428, 9894 |
214, 4947 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1779416/2
Therefore the LCM of Fractions 5128/428,1388/9894 is 889708
