Least Common Multiple of 31/93,68/40,978/47

Given numbers are 31/93,68/40,978/47

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 31,68,978

Least Common Multiple of Numerators i.e. LCM of 31,68,978 is 1030812.

GCF of Denominators means GCF of 93,40,47 as per the given fractions.

GCF of 93,40,47 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 31,68,978

LCM of Fractions 31/93,68/40,978/47 is 1030812

2 31, 68, 978
31, 34, 489

∴ So the LCM of the given numbers is 2 x 31 x 34 x 489 = 1030812

Least Common Multiple of 31,68,978 with GCF Formula

Least Common Multiple of 31,68,978 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 31,68,978 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,68,978) = 1

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

GCF(31,68,978) x common factors =1 x 2 = 2

LCM(31,68,978) = ( 31 × 68 × 978 ) / 2

LCM(31,68,978) = 2061624 / 2

LCM(31,68,978) = 1030812


Lets's calculate GCF of 93,40,47

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1030812/1

Therefore the LCM of Fractions 31/93,68/40,978/47 is 1030812
