Lets's calculate LCM of 643,6657

LCM of Fractions 643/291,6657/770 is 4280451

Given numbers has no common factors except 1. So, there LCM is their product i.e 4280451

Least Common Multiple of 643,6657 with GCF Formula

Least Common Multiple of 643,6657 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 643,6657 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(643,6657) = 1

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

GCF(643,6657) x common factors =1 x 1 = 1

LCM(643,6657) = ( 643 × 6657 ) / 1

LCM(643,6657) = 4280451 / 1

LCM(643,6657) = 4280451


Lets's calculate GCF of 291,770

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4280451/1

Therefore the LCM of Fractions 643/291,6657/770 is 4280451
