Least Common Multiple of 31/628,78/309,814/136

Given numbers are 31/628,78/309,814/136

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 31,78,814

Least Common Multiple of Numerators i.e. LCM of 31,78,814 is 984126.

GCF of Denominators means GCF of 628,309,136 as per the given fractions.

GCF of 628,309,136 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 31,78,814

LCM of Fractions 31/628,78/309,814/136 is 984126

2 31, 78, 814
31, 39, 407

∴ So the LCM of the given numbers is 2 x 31 x 39 x 407 = 984126

Least Common Multiple of 31,78,814 with GCF Formula

Least Common Multiple of 31,78,814 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 31,78,814 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,78,814) = 1

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

GCF(31,78,814) x common factors =1 x 2 = 2

LCM(31,78,814) = ( 31 × 78 × 814 ) / 2

LCM(31,78,814) = 1968252 / 2

LCM(31,78,814) = 984126


Lets's calculate GCF of 628,309,136

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 984126/1

Therefore the LCM of Fractions 31/628,78/309,814/136 is 984126
