Know Least Common Multiple of fractions 420/962, 121/189 quickly i.e. 50820 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 420/962, 121/189 is 50820.
LCM(420/962, 121/189) = 50820
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 420/962,121/189
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 420,121
Least Common Multiple of Numerators i.e. LCM of 420,121 is 50820.
GCF of Denominators means GCF of 962,189 as per the given fractions.
GCF of 962,189 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 420,121
Given numbers has no common factors except 1. So, there LCM is their product i.e 50820
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 420,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,121) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(420,121) x common factors =1 x 1 = 1
LCM(420,121) = ( 420 × 121 ) / 1
LCM(420,121) = 50820 / 1
LCM(420,121) = 50820
Lets's calculate GCF of 962,189
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 50820/1
Therefore the LCM of Fractions 420/962,121/189 is 50820
