Least Common Multiple of 70/43,69/77,424/640

Given numbers are 70/43,69/77,424/640

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 70,69,424

Least Common Multiple of Numerators i.e. LCM of 70,69,424 is 1023960.

GCF of Denominators means GCF of 43,77,640 as per the given fractions.

GCF of 43,77,640 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 70,69,424

LCM of Fractions 70/43,69/77,424/640 is 1023960

2 70, 69, 424
35, 69, 212

∴ So the LCM of the given numbers is 2 x 35 x 69 x 212 = 1023960

Least Common Multiple of 70,69,424 with GCF Formula

Least Common Multiple of 70,69,424 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 70,69,424 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,69,424) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(70,69,424) x common factors =1 x 2 = 2

LCM(70,69,424) = ( 70 × 69 × 424 ) / 2

LCM(70,69,424) = 2047920 / 2

LCM(70,69,424) = 1023960


Lets's calculate GCF of 43,77,640

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1023960/1

Therefore the LCM of Fractions 70/43,69/77,424/640 is 1023960
