GCF of Denominators means GCF of 31,387 as per the given fractions.

GCF of 31,387 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 690,3938

LCM of Fractions 690/31,3938/387 is 1358610

2 690, 3938
345, 1969

∴ So the LCM of the given numbers is 2 x 345 x 1969 = 1358610

Least Common Multiple of 690,3938 with GCF Formula

Least Common Multiple of 690,3938 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 690,3938 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(690,3938) = 2

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

GCF(690,3938) x common factors =2 x 1 = 2

LCM(690,3938) = ( 690 × 3938 ) / 2

LCM(690,3938) = 2717220 / 2

LCM(690,3938) = 1358610


Lets's calculate GCF of 31,387

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1358610/1

Therefore the LCM of Fractions 690/31,3938/387 is 1358610
