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 691,987,920

Least Common Multiple of Numerators i.e. LCM of 691,987,920 is 627455640.

GCF of Denominators means GCF of 60,40,412 as per the given fractions.

GCF of 60,40,412 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 691,987,920

LCM of Fractions 691/60,987/40,920/412 is 156863910

Given numbers has no common factors except 1. So, there LCM is their product i.e 627455640

Least Common Multiple of 691,987,920 with GCF Formula

Least Common Multiple of 691,987,920 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 691,987,920 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(691,987,920) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(691,987,920) x common factors =1 x 1 = 1

LCM(691,987,920) = ( 691 × 987 × 920 ) / 1

LCM(691,987,920) = 627455640 / 1

LCM(691,987,920) = 627455640


Lets's calculate GCF of 60,40,412

2 60, 40, 412
2 30, 20, 206
15, 10, 103

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 627455640/4

Therefore the LCM of Fractions 691/60,987/40,920/412 is 156863910
