Know Least Common Multiple of fractions 7491/97, 3171/981 quickly i.e. 7917987 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 7491/97, 3171/981 is 7917987.
LCM(7491/97, 3171/981) = 7917987
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 7491/97,3171/981
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 7491,3171
Least Common Multiple of Numerators i.e. LCM of 7491,3171 is 7917987.
GCF of Denominators means GCF of 97,981 as per the given fractions.
GCF of 97,981 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 7491,3171
3 | 7491, 3171 |
2497, 1057 |
∴ So the LCM of the given numbers is 3 x 2497 x 1057 = 7917987
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 7491,3171 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(7491,3171) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(7491,3171) x common factors =3 x 1 = 3
LCM(7491,3171) = ( 7491 × 3171 ) / 3
LCM(7491,3171) = 23753961 / 3
LCM(7491,3171) = 7917987
Lets's calculate GCF of 97,981
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7917987/1
Therefore the LCM of Fractions 7491/97,3171/981 is 7917987
