Least Common Multiple of 21/680,736/142,424/745

Given numbers are 21/680,736/142,424/745

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 21,736,424

Least Common Multiple of Numerators i.e. LCM of 21,736,424 is 819168.

GCF of Denominators means GCF of 680,142,745 as per the given fractions.

GCF of 680,142,745 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 21,736,424

LCM of Fractions 21/680,736/142,424/745 is 819168

2 21, 736, 424
2 21, 368, 212
2 21, 184, 106
21, 92, 53

∴ So the LCM of the given numbers is 2 x 2 x 2 x 21 x 92 x 53 = 819168

Least Common Multiple of 21,736,424 with GCF Formula

Least Common Multiple of 21,736,424 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 21,736,424 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,736,424) = 1

common factors(in case of two or more numbers have common factors) = 8

GCF(21,736,424) x common factors =1 x 8 = 8

LCM(21,736,424) = ( 21 × 736 × 424 ) / 8

LCM(21,736,424) = 6553344 / 8

LCM(21,736,424) = 819168


Lets's calculate GCF of 680,142,745

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 819168/1

Therefore the LCM of Fractions 21/680,736/142,424/745 is 819168
