Least Common Multiple of 70/50,14/42,872/840

Given numbers are 70/50,14/42,872/840

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 70,14,872

Least Common Multiple of Numerators i.e. LCM of 70,14,872 is 30520.

GCF of Denominators means GCF of 50,42,840 as per the given fractions.

GCF of 50,42,840 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 70,14,872

LCM of Fractions 70/50,14/42,872/840 is 15260

2 70, 14, 872
7 35, 7, 436
5, 1, 436

∴ So the LCM of the given numbers is 2 x 7 x 5 x 1 x 436 = 30520

Least Common Multiple of 70,14,872 with GCF Formula

Least Common Multiple of 70,14,872 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 70,14,872 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,14,872) = 2

common factors(in case of two or more numbers have common factors) = 14

GCF(70,14,872) x common factors =2 x 14 = 28

LCM(70,14,872) = ( 70 × 14 × 872 ) / 28

LCM(70,14,872) = 854560 / 28

LCM(70,14,872) = 30520


Lets's calculate GCF of 50,42,840

2 50, 42, 840
25, 21, 420

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 30520/2

Therefore the LCM of Fractions 70/50,14/42,872/840 is 15260
