Lets's calculate LCM of 6440,6791

LCM of Fractions 6440/298,6791/128 is 21867020

Given numbers has no common factors except 1. So, there LCM is their product i.e 43734040

Least Common Multiple of 6440,6791 with GCF Formula

Least Common Multiple of 6440,6791 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 6440,6791 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(6440,6791) = 1

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

GCF(6440,6791) x common factors =1 x 1 = 1

LCM(6440,6791) = ( 6440 × 6791 ) / 1

LCM(6440,6791) = 43734040 / 1

LCM(6440,6791) = 43734040


Lets's calculate GCF of 298,128

2 298, 128
149, 64

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 43734040/2

Therefore the LCM of Fractions 6440/298,6791/128 is 21867020
