Know Least Common Multiple of fractions 622/398, 460/139 quickly i.e. 143060 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 622/398, 460/139 is 143060.
LCM(622/398, 460/139) = 143060
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 622/398,460/139
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 622,460
Least Common Multiple of Numerators i.e. LCM of 622,460 is 143060.
GCF of Denominators means GCF of 398,139 as per the given fractions.
GCF of 398,139 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 622,460
2 | 622, 460 |
311, 230 |
∴ So the LCM of the given numbers is 2 x 311 x 230 = 143060
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 622,460 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(622,460) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(622,460) x common factors =2 x 1 = 2
LCM(622,460) = ( 622 × 460 ) / 2
LCM(622,460) = 286120 / 2
LCM(622,460) = 143060
Lets's calculate GCF of 398,139
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 143060/1
Therefore the LCM of Fractions 622/398,460/139 is 143060
