Least Common Multiple of 78/23,159/77,685/557

Given numbers are 78/23,159/77,685/557

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 78,159,685

Least Common Multiple of Numerators i.e. LCM of 78,159,685 is 2831790.

GCF of Denominators means GCF of 23,77,557 as per the given fractions.

GCF of 23,77,557 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 78,159,685

LCM of Fractions 78/23,159/77,685/557 is 2831790

3 78, 159, 685
26, 53, 685

∴ So the LCM of the given numbers is 3 x 26 x 53 x 685 = 2831790

Least Common Multiple of 78,159,685 with GCF Formula

Least Common Multiple of 78,159,685 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 78,159,685 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,159,685) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(78,159,685) x common factors =1 x 3 = 3

LCM(78,159,685) = ( 78 × 159 × 685 ) / 3

LCM(78,159,685) = 8495370 / 3

LCM(78,159,685) = 2831790


Lets's calculate GCF of 23,77,557

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2831790/1

Therefore the LCM of Fractions 78/23,159/77,685/557 is 2831790
