Know Least Common Multiple of fractions 531/123, 1720/931 quickly i.e. 913320 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 531/123, 1720/931 is 913320.
LCM(531/123, 1720/931) = 913320
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 531/123,1720/931
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 531,1720
Least Common Multiple of Numerators i.e. LCM of 531,1720 is 913320.
GCF of Denominators means GCF of 123,931 as per the given fractions.
GCF of 123,931 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 531,1720
Given numbers has no common factors except 1. So, there LCM is their product i.e 913320
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 531,1720 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(531,1720) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(531,1720) x common factors =1 x 1 = 1
LCM(531,1720) = ( 531 × 1720 ) / 1
LCM(531,1720) = 913320 / 1
LCM(531,1720) = 913320
Lets's calculate GCF of 123,931
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 913320/1
Therefore the LCM of Fractions 531/123,1720/931 is 913320
