Lets's calculate LCM of 389,398

LCM of Fractions 389/86,398/1915 is 154822

Given numbers has no common factors except 1. So, there LCM is their product i.e 154822

Least Common Multiple of 389,398 with GCF Formula

Least Common Multiple of 389,398 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 389,398 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(389,398) = 1

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

GCF(389,398) x common factors =1 x 1 = 1

LCM(389,398) = ( 389 × 398 ) / 1

LCM(389,398) = 154822 / 1

LCM(389,398) = 154822


Lets's calculate GCF of 86,1915

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 154822/1

Therefore the LCM of Fractions 389/86,398/1915 is 154822
