Least Common Multiple of 7809/42,7270/820

Given numbers are 7809/42,7270/820

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 7809,7270

Least Common Multiple of Numerators i.e. LCM of 7809,7270 is 56771430.

GCF of Denominators means GCF of 42,820 as per the given fractions.

GCF of 42,820 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 7809,7270

LCM of Fractions 7809/42,7270/820 is 28385715

Given numbers has no common factors except 1. So, there LCM is their product i.e 56771430

Least Common Multiple of 7809,7270 with GCF Formula

Least Common Multiple of 7809,7270 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 7809,7270 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(7809,7270) = 1

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

GCF(7809,7270) x common factors =1 x 1 = 1

LCM(7809,7270) = ( 7809 × 7270 ) / 1

LCM(7809,7270) = 56771430 / 1

LCM(7809,7270) = 56771430


Lets's calculate GCF of 42,820

2 42, 820
21, 410

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 56771430/2

Therefore the LCM of Fractions 7809/42,7270/820 is 28385715
