GCF of Denominators means GCF of 470,678 as per the given fractions.

GCF of 470,678 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 987,3997

LCM of Fractions 987/470,3997/678 is 563577/2

7 987, 3997
141, 571

∴ So the LCM of the given numbers is 7 x 141 x 571 = 563577

Least Common Multiple of 987,3997 with GCF Formula

Least Common Multiple of 987,3997 with GCF Formula

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 987,3997 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(987,3997) = 7

common factors(in case of two or more numbers have common factors) = 1

GCF(987,3997) x common factors =7 x 1 = 7

LCM(987,3997) = ( 987 × 3997 ) / 7

LCM(987,3997) = 3945039 / 7

LCM(987,3997) = 563577


Lets's calculate GCF of 470,678

2 470, 678
235, 339

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 563577/2

Therefore the LCM of Fractions 987/470,3997/678 is 563577/2
