Know Least Common Multiple of fractions 31/209, 4288/6920 quickly i.e. 132928 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 31/209, 4288/6920 is 132928.
LCM(31/209, 4288/6920) = 132928
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 31/209,4288/6920
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 31,4288
Least Common Multiple of Numerators i.e. LCM of 31,4288 is 132928.
GCF of Denominators means GCF of 209,6920 as per the given fractions.
GCF of 209,6920 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 31,4288
Given numbers has no common factors except 1. So, there LCM is their product i.e 132928
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 31,4288 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,4288) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,4288) x common factors =1 x 1 = 1
LCM(31,4288) = ( 31 × 4288 ) / 1
LCM(31,4288) = 132928 / 1
LCM(31,4288) = 132928
Lets's calculate GCF of 209,6920
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 132928/1
Therefore the LCM of Fractions 31/209,4288/6920 is 132928
