Lets's calculate LCM of 686,1247

LCM of Fractions 686/389,1247/872 is 855442

Given numbers has no common factors except 1. So, there LCM is their product i.e 855442

Least Common Multiple of 686,1247 with GCF Formula

Least Common Multiple of 686,1247 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 686,1247 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(686,1247) = 1

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

GCF(686,1247) x common factors =1 x 1 = 1

LCM(686,1247) = ( 686 × 1247 ) / 1

LCM(686,1247) = 855442 / 1

LCM(686,1247) = 855442


Lets's calculate GCF of 389,872

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 855442/1

Therefore the LCM of Fractions 686/389,1247/872 is 855442
