Lets's calculate LCM of 31,60,389

Given numbers has no common factors except 1. So, there LCM is their product i.e 723540

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/723540

Therefore, the GCF of Fractions 51/31,90/60,52/389 is 1/723540

Least Common Multiple of 31,60,389 with GCF Formula

Least Common Multiple of 31,60,389 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 31,60,389 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,60,389) = 1

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

GCF(31,60,389) x common factors =1 x 1 = 1

LCM(31,60,389) = ( 31 × 60 × 389 ) / 1

LCM(31,60,389) = 723540 / 1

LCM(31,60,389) = 723540
