Lets's calculate LCM of 690,449

Given numbers has no common factors except 1. So, there LCM is their product i.e 309810

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/309810

Therefore, the GCF of Fractions 451/690,242/449 is 11/309810

Least Common Multiple of 690,449 with GCF Formula

Least Common Multiple of 690,449 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 690,449 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(690,449) = 1

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

GCF(690,449) x common factors =1 x 1 = 1

LCM(690,449) = ( 690 × 449 ) / 1

LCM(690,449) = 309810 / 1

LCM(690,449) = 309810
