Lets's calculate LCM of 7891,1687

LCM of Fractions 7891/531,1687/686 is 13312117

Given numbers has no common factors except 1. So, there LCM is their product i.e 13312117

Least Common Multiple of 7891,1687 with GCF Formula

Least Common Multiple of 7891,1687 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 7891,1687 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(7891,1687) = 1

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

GCF(7891,1687) x common factors =1 x 1 = 1

LCM(7891,1687) = ( 7891 × 1687 ) / 1

LCM(7891,1687) = 13312117 / 1

LCM(7891,1687) = 13312117


Lets's calculate GCF of 531,686

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 13312117/1

Therefore the LCM of Fractions 7891/531,1687/686 is 13312117
