Least Common Multiple of 8091/68,7708/640

Given numbers are 8091/68,7708/640

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 8091,7708

Least Common Multiple of Numerators i.e. LCM of 8091,7708 is 62365428.

GCF of Denominators means GCF of 68,640 as per the given fractions.

GCF of 68,640 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 8091,7708

LCM of Fractions 8091/68,7708/640 is 15591357

Given numbers has no common factors except 1. So, there LCM is their product i.e 62365428

Least Common Multiple of 8091,7708 with GCF Formula

Least Common Multiple of 8091,7708 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 8091,7708 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(8091,7708) = 1

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

GCF(8091,7708) x common factors =1 x 1 = 1

LCM(8091,7708) = ( 8091 × 7708 ) / 1

LCM(8091,7708) = 62365428 / 1

LCM(8091,7708) = 62365428


Lets's calculate GCF of 68,640

2 68, 640
2 34, 320
17, 160

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 62365428/4

Therefore the LCM of Fractions 8091/68,7708/640 is 15591357
