Least Common Multiple of 689/128,3714/426

Given numbers are 689/128,3714/426

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 689,3714

Least Common Multiple of Numerators i.e. LCM of 689,3714 is 2558946.

GCF of Denominators means GCF of 128,426 as per the given fractions.

GCF of 128,426 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 689,3714

LCM of Fractions 689/128,3714/426 is 1279473

Given numbers has no common factors except 1. So, there LCM is their product i.e 2558946

Least Common Multiple of 689,3714 with GCF Formula

Least Common Multiple of 689,3714 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 689,3714 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(689,3714) = 1

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

GCF(689,3714) x common factors =1 x 1 = 1

LCM(689,3714) = ( 689 × 3714 ) / 1

LCM(689,3714) = 2558946 / 1

LCM(689,3714) = 2558946


Lets's calculate GCF of 128,426

2 128, 426
64, 213

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2558946/2

Therefore the LCM of Fractions 689/128,3714/426 is 1279473
