Lets's calculate LCM of 6489,8129

LCM of Fractions 6489/21,8129/637 is 7535583

Given numbers has no common factors except 1. So, there LCM is their product i.e 52749081

Least Common Multiple of 6489,8129 with GCF Formula

Least Common Multiple of 6489,8129 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 6489,8129 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(6489,8129) = 1

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

GCF(6489,8129) x common factors =1 x 1 = 1

LCM(6489,8129) = ( 6489 × 8129 ) / 1

LCM(6489,8129) = 52749081 / 1

LCM(6489,8129) = 52749081


Lets's calculate GCF of 21,637

7 21, 637
3, 91

∴ So the GCF of the given numbers is 7 = 7

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 52749081/7

Therefore the LCM of Fractions 6489/21,8129/637 is 7535583
