Lets's calculate LCM of 87,7889

LCM of Fractions 87/490,7889/7939 is 686343

Given numbers has no common factors except 1. So, there LCM is their product i.e 686343

Least Common Multiple of 87,7889 with GCF Formula

Least Common Multiple of 87,7889 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 87,7889 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(87,7889) = 1

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

GCF(87,7889) x common factors =1 x 1 = 1

LCM(87,7889) = ( 87 × 7889 ) / 1

LCM(87,7889) = 686343 / 1

LCM(87,7889) = 686343


Lets's calculate GCF of 490,7939

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 686343/1

Therefore the LCM of Fractions 87/490,7889/7939 is 686343
