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 3840,3659

Least Common Multiple of Numerators i.e. LCM of 3840,3659 is 14050560.

GCF of Denominators means GCF of 645,714 as per the given fractions.

GCF of 645,714 is 3 as it is the largest common factor for these numbers.

Lets's calculate LCM of 3840,3659

LCM of Fractions 3840/645,3659/714 is 4683520

Given numbers has no common factors except 1. So, there LCM is their product i.e 14050560

Least Common Multiple of 3840,3659 with GCF Formula

Least Common Multiple of 3840,3659 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 3840,3659 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(3840,3659) = 1

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

GCF(3840,3659) x common factors =1 x 1 = 1

LCM(3840,3659) = ( 3840 × 3659 ) / 1

LCM(3840,3659) = 14050560 / 1

LCM(3840,3659) = 14050560


Lets's calculate GCF of 645,714

3 645, 714
215, 238

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 14050560/3

Therefore the LCM of Fractions 3840/645,3659/714 is 4683520
