LCM of:

Least Common Multiple of 47/78,11/54,691/308

Given numbers are 47/78,11/54,691/308

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 47,11,691

Least Common Multiple of Numerators i.e. LCM of 47,11,691 is 357247.

GCF of Denominators means GCF of 78,54,308 as per the given fractions.

GCF of 78,54,308 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 47,11,691

LCM of Fractions 47/78,11/54,691/308 is 357247/2

Given numbers has no common factors except 1. So, there LCM is their product i.e 357247

Least Common Multiple of 47,11,691 with GCF Formula

Least Common Multiple of 47,11,691 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 47,11,691 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(47,11,691) = 1

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

GCF(47,11,691) x common factors =1 x 1 = 1

LCM(47,11,691) = ( 47 × 11 × 691 ) / 1

LCM(47,11,691) = 357247 / 1

LCM(47,11,691) = 357247


Lets's calculate GCF of 78,54,308

2 78, 54, 308
39, 27, 154

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 357247/2

Therefore the LCM of Fractions 47/78,11/54,691/308 is 357247/2
