Lets's calculate LCM of 1631,1878

LCM of Fractions 1631/689,1878/672 is 3063018

Given numbers has no common factors except 1. So, there LCM is their product i.e 3063018

Least Common Multiple of 1631,1878 with GCF Formula

Least Common Multiple of 1631,1878 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 1631,1878 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1631,1878) = 1

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

GCF(1631,1878) x common factors =1 x 1 = 1

LCM(1631,1878) = ( 1631 × 1878 ) / 1

LCM(1631,1878) = 3063018 / 1

LCM(1631,1878) = 3063018


Lets's calculate GCF of 689,672

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3063018/1

Therefore the LCM of Fractions 1631/689,1878/672 is 3063018
