Know Least Common Multiple of fractions 331/486, 428/642 quickly i.e. 141668/6 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 331/486, 428/642 is 141668/6.
LCM(331/486, 428/642) = 141668/6
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 331/486,428/642
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 331,428
Least Common Multiple of Numerators i.e. LCM of 331,428 is 141668.
GCF of Denominators means GCF of 486,642 as per the given fractions.
GCF of 486,642 is 6 as it is the largest common factor for these numbers.
Lets's calculate LCM of 331,428
Given numbers has no common factors except 1. So, there LCM is their product i.e 141668
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 331,428 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(331,428) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(331,428) x common factors =1 x 1 = 1
LCM(331,428) = ( 331 × 428 ) / 1
LCM(331,428) = 141668 / 1
LCM(331,428) = 141668
Lets's calculate GCF of 486,642
2 | 486, 642 |
3 | 243, 321 |
81, 107 |
∴ So the GCF of the given numbers is 2 x 3 = 6
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 141668/6
Therefore the LCM of Fractions 331/486,428/642 is 141668/6
