Least Common Multiple of 56/86,30/34,761/421

Given numbers are 56/86,30/34,761/421

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 56,30,761

Least Common Multiple of Numerators i.e. LCM of 56,30,761 is 639240.

GCF of Denominators means GCF of 86,34,421 as per the given fractions.

GCF of 86,34,421 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 56,30,761

LCM of Fractions 56/86,30/34,761/421 is 639240

2 56, 30, 761
28, 15, 761

∴ So the LCM of the given numbers is 2 x 28 x 15 x 761 = 639240

Least Common Multiple of 56,30,761 with GCF Formula

Least Common Multiple of 56,30,761 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 56,30,761 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(56,30,761) = 1

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

GCF(56,30,761) x common factors =1 x 2 = 2

LCM(56,30,761) = ( 56 × 30 × 761 ) / 2

LCM(56,30,761) = 1278480 / 2

LCM(56,30,761) = 639240


Lets's calculate GCF of 86,34,421

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 639240/1

Therefore the LCM of Fractions 56/86,30/34,761/421 is 639240
