Lets's calculate LCM of 131,451

Given numbers has no common factors except 1. So, there LCM is their product i.e 59081

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/59081

Therefore, the GCF of Fractions 78/131,678/451 is 6/59081

Least Common Multiple of 131,451 with GCF Formula

Least Common Multiple of 131,451 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 131,451 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(131,451) = 1

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

GCF(131,451) x common factors =1 x 1 = 1

LCM(131,451) = ( 131 × 451 ) / 1

LCM(131,451) = 59081 / 1

LCM(131,451) = 59081
