Lets's calculate LCM of 81,940

Given numbers has no common factors except 1. So, there LCM is their product i.e 76140

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/76140

Therefore, the GCF of Fractions 507/81,258/940 is 3/76140

Least Common Multiple of 81,940 with GCF Formula

Least Common Multiple of 81,940 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 81,940 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,940) = 1

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

GCF(81,940) x common factors =1 x 1 = 1

LCM(81,940) = ( 81 × 940 ) / 1

LCM(81,940) = 76140 / 1

LCM(81,940) = 76140
