Lets's calculate LCM of 666,643

LCM of Fractions 666/989,643/281 is 428238

Given numbers has no common factors except 1. So, there LCM is their product i.e 428238

Least Common Multiple of 666,643 with GCF Formula

Least Common Multiple of 666,643 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 666,643 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(666,643) = 1

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

GCF(666,643) x common factors =1 x 1 = 1

LCM(666,643) = ( 666 × 643 ) / 1

LCM(666,643) = 428238 / 1

LCM(666,643) = 428238


Lets's calculate GCF of 989,281

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 428238/1

Therefore the LCM of Fractions 666/989,643/281 is 428238
