Least Common Multiple of 28/940,656/478,615/989

Given numbers are 28/940,656/478,615/989

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 28,656,615

Least Common Multiple of Numerators i.e. LCM of 28,656,615 is 68880.

GCF of Denominators means GCF of 940,478,989 as per the given fractions.

GCF of 940,478,989 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 28,656,615

LCM of Fractions 28/940,656/478,615/989 is 68880

2 28, 656, 615
2 14, 328, 615
41 7, 164, 615
7, 4, 15

∴ So the LCM of the given numbers is 2 x 2 x 41 x 7 x 4 x 15 = 68880

Least Common Multiple of 28,656,615 with GCF Formula

Least Common Multiple of 28,656,615 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 28,656,615 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(28,656,615) = 1

common factors(in case of two or more numbers have common factors) = 164

GCF(28,656,615) x common factors =1 x 164 = 164

LCM(28,656,615) = ( 28 × 656 × 615 ) / 164

LCM(28,656,615) = 11296320 / 164

LCM(28,656,615) = 68880


Lets's calculate GCF of 940,478,989

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 68880/1

Therefore the LCM of Fractions 28/940,656/478,615/989 is 68880
