Know Least Common Multiple of fractions 7941/393, 3091/981 quickly i.e. 8181877 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 7941/393, 3091/981 is 8181877.
LCM(7941/393, 3091/981) = 8181877
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 7941/393,3091/981
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 7941,3091
Least Common Multiple of Numerators i.e. LCM of 7941,3091 is 24545631.
GCF of Denominators means GCF of 393,981 as per the given fractions.
GCF of 393,981 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 7941,3091
Given numbers has no common factors except 1. So, there LCM is their product i.e 24545631
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 7941,3091 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(7941,3091) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(7941,3091) x common factors =1 x 1 = 1
LCM(7941,3091) = ( 7941 × 3091 ) / 1
LCM(7941,3091) = 24545631 / 1
LCM(7941,3091) = 24545631
Lets's calculate GCF of 393,981
3 | 393, 981 |
131, 327 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 24545631/3
Therefore the LCM of Fractions 7941/393,3091/981 is 8181877
