Given numbers are 402/19,398/21,906/636

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 402,398,906

Least Common Multiple of Numerators i.e. LCM of 402,398,906 is 12079698.

GCF of Denominators means GCF of 19,21,636 as per the given fractions.

GCF of 19,21,636 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 402,398,906

LCM of Fractions 402/19,398/21,906/636 is 12079698

2 402, 398, 906
3 201, 199, 453
67, 199, 151

∴ So the LCM of the given numbers is 2 x 3 x 67 x 199 x 151 = 12079698

Least Common Multiple of 402,398,906 with GCF Formula

Least Common Multiple of 402,398,906 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 402,398,906 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(402,398,906) = 2

common factors(in case of two or more numbers have common factors) = 6

GCF(402,398,906) x common factors =2 x 6 = 12

LCM(402,398,906) = ( 402 × 398 × 906 ) / 12

LCM(402,398,906) = 144956376 / 12

LCM(402,398,906) = 12079698


Lets's calculate GCF of 19,21,636

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 12079698/1

Therefore the LCM of Fractions 402/19,398/21,906/636 is 12079698
