Lets's calculate LCM of 486,523

Given numbers has no common factors except 1. So, there LCM is their product i.e 254178

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/254178

Therefore, the GCF of Fractions 840/486,9142/523 is 14/254178

Least Common Multiple of 486,523 with GCF Formula

Least Common Multiple of 486,523 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 486,523 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(486,523) = 1

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

GCF(486,523) x common factors =1 x 1 = 1

LCM(486,523) = ( 486 × 523 ) / 1

LCM(486,523) = 254178 / 1

LCM(486,523) = 254178
