Lets's calculate LCM of 31,2678

LCM of Fractions 31/781,2678/6820 is 83018/11

Given numbers has no common factors except 1. So, there LCM is their product i.e 83018

Least Common Multiple of 31,2678 with GCF Formula

Least Common Multiple of 31,2678 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 31,2678 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,2678) = 1

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

GCF(31,2678) x common factors =1 x 1 = 1

LCM(31,2678) = ( 31 × 2678 ) / 1

LCM(31,2678) = 83018 / 1

LCM(31,2678) = 83018


Lets's calculate GCF of 781,6820

11 781, 6820
71, 620

∴ So the GCF of the given numbers is 11 = 11

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 83018/11

Therefore the LCM of Fractions 31/781,2678/6820 is 83018/11
