Lets's calculate LCM of 997,489

LCM of Fractions 997/686,489/531 is 487533

Given numbers has no common factors except 1. So, there LCM is their product i.e 487533

Least Common Multiple of 997,489 with GCF Formula

Least Common Multiple of 997,489 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 997,489 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(997,489) = 1

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

GCF(997,489) x common factors =1 x 1 = 1

LCM(997,489) = ( 997 × 489 ) / 1

LCM(997,489) = 487533 / 1

LCM(997,489) = 487533


Lets's calculate GCF of 686,531

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 487533/1

Therefore the LCM of Fractions 997/686,489/531 is 487533
