Know Least Common Multiple of fractions 3940/42, 3631/913 quickly i.e. 14306140 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 3940/42, 3631/913 is 14306140.
LCM(3940/42, 3631/913) = 14306140
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 3940/42,3631/913
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 3940,3631
Least Common Multiple of Numerators i.e. LCM of 3940,3631 is 14306140.
GCF of Denominators means GCF of 42,913 as per the given fractions.
GCF of 42,913 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 3940,3631
Given numbers has no common factors except 1. So, there LCM is their product i.e 14306140
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 3940,3631 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(3940,3631) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(3940,3631) x common factors =1 x 1 = 1
LCM(3940,3631) = ( 3940 × 3631 ) / 1
LCM(3940,3631) = 14306140 / 1
LCM(3940,3631) = 14306140
Lets's calculate GCF of 42,913
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 14306140/1
Therefore the LCM of Fractions 3940/42,3631/913 is 14306140
