Least Common Multiple of 781/195,7140/309

Given numbers are 781/195,7140/309

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 781,7140

Least Common Multiple of Numerators i.e. LCM of 781,7140 is 5576340.

GCF of Denominators means GCF of 195,309 as per the given fractions.

GCF of 195,309 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 781,7140

LCM of Fractions 781/195,7140/309 is 1858780

Given numbers has no common factors except 1. So, there LCM is their product i.e 5576340

Least Common Multiple of 781,7140 with GCF Formula

Least Common Multiple of 781,7140 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 781,7140 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(781,7140) = 1

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

GCF(781,7140) x common factors =1 x 1 = 1

LCM(781,7140) = ( 781 × 7140 ) / 1

LCM(781,7140) = 5576340 / 1

LCM(781,7140) = 5576340


Lets's calculate GCF of 195,309

3 195, 309
65, 103

∴ So the GCF of the given numbers is 3 = 3

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 5576340/3

Therefore the LCM of Fractions 781/195,7140/309 is 1858780
