Lets's calculate LCM of 1643,1939

LCM of Fractions 1643/605,1939/681 is 3185777

Given numbers has no common factors except 1. So, there LCM is their product i.e 3185777

Least Common Multiple of 1643,1939 with GCF Formula

Least Common Multiple of 1643,1939 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 1643,1939 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1643,1939) = 1

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

GCF(1643,1939) x common factors =1 x 1 = 1

LCM(1643,1939) = ( 1643 × 1939 ) / 1

LCM(1643,1939) = 3185777 / 1

LCM(1643,1939) = 3185777


Lets's calculate GCF of 605,681

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3185777/1

Therefore the LCM of Fractions 1643/605,1939/681 is 3185777
