GCF of Denominators means GCF of 42,19,875 as per the given fractions.

GCF of 42,19,875 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 398,662,785

LCM of Fractions 398/42,662/19,785/875 is 103414330

2 398, 662, 785
199, 331, 785

∴ So the LCM of the given numbers is 2 x 199 x 331 x 785 = 103414330

Least Common Multiple of 398,662,785 with GCF Formula

Least Common Multiple of 398,662,785 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 398,662,785 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(398,662,785) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(398,662,785) x common factors =1 x 2 = 2

LCM(398,662,785) = ( 398 × 662 × 785 ) / 2

LCM(398,662,785) = 206828660 / 2

LCM(398,662,785) = 103414330


Lets's calculate GCF of 42,19,875

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 103414330/1

Therefore the LCM of Fractions 398/42,662/19,785/875 is 103414330
