Know Least Common Multiple of fractions 40/391, 1977/5198 quickly i.e. 79080/23 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 40/391, 1977/5198 is 79080/23.
LCM(40/391, 1977/5198) = 79080/23
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 40/391,1977/5198
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 40,1977
Least Common Multiple of Numerators i.e. LCM of 40,1977 is 79080.
GCF of Denominators means GCF of 391,5198 as per the given fractions.
GCF of 391,5198 is 23 as it is the largest common factor for these numbers.
Lets's calculate LCM of 40,1977
Given numbers has no common factors except 1. So, there LCM is their product i.e 79080
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 40,1977 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,1977) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(40,1977) x common factors =1 x 1 = 1
LCM(40,1977) = ( 40 × 1977 ) / 1
LCM(40,1977) = 79080 / 1
LCM(40,1977) = 79080
Lets's calculate GCF of 391,5198
23 | 391, 5198 |
17, 226 |
∴ So the GCF of the given numbers is 23 = 23
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 79080/23
Therefore the LCM of Fractions 40/391,1977/5198 is 79080/23
