Least Common Multiple of 3954/84,3781/142

Given numbers are 3954/84,3781/142

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 3954,3781

Least Common Multiple of Numerators i.e. LCM of 3954,3781 is 14950074.

GCF of Denominators means GCF of 84,142 as per the given fractions.

GCF of 84,142 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 3954,3781

LCM of Fractions 3954/84,3781/142 is 7475037

Given numbers has no common factors except 1. So, there LCM is their product i.e 14950074

Least Common Multiple of 3954,3781 with GCF Formula

Least Common Multiple of 3954,3781 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 3954,3781 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(3954,3781) = 1

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

GCF(3954,3781) x common factors =1 x 1 = 1

LCM(3954,3781) = ( 3954 × 3781 ) / 1

LCM(3954,3781) = 14950074 / 1

LCM(3954,3781) = 14950074


Lets's calculate GCF of 84,142

2 84, 142
42, 71

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 14950074/2

Therefore the LCM of Fractions 3954/84,3781/142 is 7475037
