LCM of:

Least Common Multiple of 687/663,1402/665

Given numbers are 687/663,1402/665

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 687,1402

Least Common Multiple of Numerators i.e. LCM of 687,1402 is 963174.

GCF of Denominators means GCF of 663,665 as per the given fractions.

GCF of 663,665 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 687,1402

LCM of Fractions 687/663,1402/665 is 963174

Given numbers has no common factors except 1. So, there LCM is their product i.e 963174

Least Common Multiple of 687,1402 with GCF Formula

Least Common Multiple of 687,1402 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 687,1402 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(687,1402) = 1

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

GCF(687,1402) x common factors =1 x 1 = 1

LCM(687,1402) = ( 687 × 1402 ) / 1

LCM(687,1402) = 963174 / 1

LCM(687,1402) = 963174


Lets's calculate GCF of 663,665

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 963174/1

Therefore the LCM of Fractions 687/663,1402/665 is 963174
