LCM of:

Least Common Multiple of 221/841,1390/857

Given numbers are 221/841,1390/857

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 221,1390

Least Common Multiple of Numerators i.e. LCM of 221,1390 is 307190.

GCF of Denominators means GCF of 841,857 as per the given fractions.

GCF of 841,857 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 221,1390

LCM of Fractions 221/841,1390/857 is 307190

Given numbers has no common factors except 1. So, there LCM is their product i.e 307190

Least Common Multiple of 221,1390 with GCF Formula

Least Common Multiple of 221,1390 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 221,1390 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(221,1390) = 1

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

GCF(221,1390) x common factors =1 x 1 = 1

LCM(221,1390) = ( 221 × 1390 ) / 1

LCM(221,1390) = 307190 / 1

LCM(221,1390) = 307190


Lets's calculate GCF of 841,857

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 307190/1

Therefore the LCM of Fractions 221/841,1390/857 is 307190
