LCM of:

Least Common Multiple of 515/221,781/401

Given numbers are 515/221,781/401

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 515,781

Least Common Multiple of Numerators i.e. LCM of 515,781 is 402215.

GCF of Denominators means GCF of 221,401 as per the given fractions.

GCF of 221,401 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 515,781

LCM of Fractions 515/221,781/401 is 402215

Given numbers has no common factors except 1. So, there LCM is their product i.e 402215

Least Common Multiple of 515,781 with GCF Formula

Least Common Multiple of 515,781 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 515,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(515,781) = 1

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

GCF(515,781) x common factors =1 x 1 = 1

LCM(515,781) = ( 515 × 781 ) / 1

LCM(515,781) = 402215 / 1

LCM(515,781) = 402215


Lets's calculate GCF of 221,401

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 402215/1

Therefore the LCM of Fractions 515/221,781/401 is 402215
