Know Least Common Multiple of fractions 1931/79, 1951/138 quickly i.e. 3767381 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 1931/79, 1951/138 is 3767381.
LCM(1931/79, 1951/138) = 3767381
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 1931/79,1951/138
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 1931,1951
Least Common Multiple of Numerators i.e. LCM of 1931,1951 is 3767381.
GCF of Denominators means GCF of 79,138 as per the given fractions.
GCF of 79,138 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 1931,1951
Given numbers has no common factors except 1. So, there LCM is their product i.e 3767381
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 1931,1951 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(1931,1951) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(1931,1951) x common factors =1 x 1 = 1
LCM(1931,1951) = ( 1931 × 1951 ) / 1
LCM(1931,1951) = 3767381 / 1
LCM(1931,1951) = 3767381
Lets's calculate GCF of 79,138
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3767381/1
Therefore the LCM of Fractions 1931/79,1951/138 is 3767381
