Lets's calculate LCM of 34,57,389

Given numbers has no common factors except 1. So, there LCM is their product i.e 753882

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/753882

Therefore, the GCF of Fractions 40/34,28/57,328/389 is 4/753882

Least Common Multiple of 34,57,389 with GCF Formula

Least Common Multiple of 34,57,389 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 34,57,389 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(34,57,389) = 1

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

GCF(34,57,389) x common factors =1 x 1 = 1

LCM(34,57,389) = ( 34 × 57 × 389 ) / 1

LCM(34,57,389) = 753882 / 1

LCM(34,57,389) = 753882
