Lets's calculate LCM of 40,57,289

Given numbers has no common factors except 1. So, there LCM is their product i.e 658920

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/658920

Therefore, the GCF of Fractions 50/40,30/57,817/289 is 1/658920

Least Common Multiple of 40,57,289 with GCF Formula

Least Common Multiple of 40,57,289 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 40,57,289 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,57,289) = 1

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

GCF(40,57,289) x common factors =1 x 1 = 1

LCM(40,57,289) = ( 40 × 57 × 289 ) / 1

LCM(40,57,289) = 658920 / 1

LCM(40,57,289) = 658920
