Least Common Multiple of 289/644,1021/676

Given numbers are 289/644,1021/676

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 289,1021

Least Common Multiple of Numerators i.e. LCM of 289,1021 is 295069.

GCF of Denominators means GCF of 644,676 as per the given fractions.

GCF of 644,676 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 289,1021

LCM of Fractions 289/644,1021/676 is 295069/4

Given numbers has no common factors except 1. So, there LCM is their product i.e 295069

Least Common Multiple of 289,1021 with GCF Formula

Least Common Multiple of 289,1021 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 289,1021 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(289,1021) = 1

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

GCF(289,1021) x common factors =1 x 1 = 1

LCM(289,1021) = ( 289 × 1021 ) / 1

LCM(289,1021) = 295069 / 1

LCM(289,1021) = 295069


Lets's calculate GCF of 644,676

2 644, 676
2 322, 338
161, 169

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 295069/4

Therefore the LCM of Fractions 289/644,1021/676 is 295069/4
