Least Common Multiple of 647/84,438/3070

Given numbers are 647/84,438/3070

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 647,438

Least Common Multiple of Numerators i.e. LCM of 647,438 is 283386.

GCF of Denominators means GCF of 84,3070 as per the given fractions.

GCF of 84,3070 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 647,438

LCM of Fractions 647/84,438/3070 is 141693

Given numbers has no common factors except 1. So, there LCM is their product i.e 283386

Least Common Multiple of 647,438 with GCF Formula

Least Common Multiple of 647,438 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 647,438 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(647,438) = 1

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

GCF(647,438) x common factors =1 x 1 = 1

LCM(647,438) = ( 647 × 438 ) / 1

LCM(647,438) = 283386 / 1

LCM(647,438) = 283386


Lets's calculate GCF of 84,3070

2 84, 3070
42, 1535

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 283386/2

Therefore the LCM of Fractions 647/84,438/3070 is 141693
