Least Common Multiple of 77/78,812/20,404/887

Given numbers are 77/78,812/20,404/887

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 77,812,404

Least Common Multiple of Numerators i.e. LCM of 77,812,404 is 902132.

GCF of Denominators means GCF of 78,20,887 as per the given fractions.

GCF of 78,20,887 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 77,812,404

LCM of Fractions 77/78,812/20,404/887 is 902132

2 77, 812, 404
2 77, 406, 202
7 77, 203, 101
11, 29, 101

∴ So the LCM of the given numbers is 2 x 2 x 7 x 11 x 29 x 101 = 902132

Least Common Multiple of 77,812,404 with GCF Formula

Least Common Multiple of 77,812,404 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 77,812,404 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,812,404) = 1

common factors(in case of two or more numbers have common factors) = 28

GCF(77,812,404) x common factors =1 x 28 = 28

LCM(77,812,404) = ( 77 × 812 × 404 ) / 28

LCM(77,812,404) = 25259696 / 28

LCM(77,812,404) = 902132


Lets's calculate GCF of 78,20,887

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 902132/1

Therefore the LCM of Fractions 77/78,812/20,404/887 is 902132
