Least Common Multiple of 74/64,868/79,680/389

Given numbers are 74/64,868/79,680/389

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 74,868,680

Least Common Multiple of Numerators i.e. LCM of 74,868,680 is 5459720.

GCF of Denominators means GCF of 64,79,389 as per the given fractions.

GCF of 64,79,389 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 74,868,680

LCM of Fractions 74/64,868/79,680/389 is 5459720

2 74, 868, 680
2 37, 434, 340
37, 217, 170

∴ So the LCM of the given numbers is 2 x 2 x 37 x 217 x 170 = 5459720

Least Common Multiple of 74,868,680 with GCF Formula

Least Common Multiple of 74,868,680 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 74,868,680 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(74,868,680) = 2

common factors(in case of two or more numbers have common factors) = 4

GCF(74,868,680) x common factors =2 x 4 = 8

LCM(74,868,680) = ( 74 × 868 × 680 ) / 8

LCM(74,868,680) = 43677760 / 8

LCM(74,868,680) = 5459720


Lets's calculate GCF of 64,79,389

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 5459720/1

Therefore the LCM of Fractions 74/64,868/79,680/389 is 5459720
