LCM of:

Least Common Multiple of 20/687,4013/4070

Given numbers are 20/687,4013/4070

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 20,4013

Least Common Multiple of Numerators i.e. LCM of 20,4013 is 80260.

GCF of Denominators means GCF of 687,4070 as per the given fractions.

GCF of 687,4070 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 20,4013

LCM of Fractions 20/687,4013/4070 is 80260

Given numbers has no common factors except 1. So, there LCM is their product i.e 80260

Least Common Multiple of 20,4013 with GCF Formula

Least Common Multiple of 20,4013 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 20,4013 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,4013) = 1

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

GCF(20,4013) x common factors =1 x 1 = 1

LCM(20,4013) = ( 20 × 4013 ) / 1

LCM(20,4013) = 80260 / 1

LCM(20,4013) = 80260


Lets's calculate GCF of 687,4070

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 80260/1

Therefore the LCM of Fractions 20/687,4013/4070 is 80260
