Lets's calculate LCM of 51,19,826

Given numbers has no common factors except 1. So, there LCM is their product i.e 800394

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/800394

Therefore, the GCF of Fractions 42/51,686/19,378/826 is 14/800394

Least Common Multiple of 51,19,826 with GCF Formula

Least Common Multiple of 51,19,826 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 51,19,826 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(51,19,826) = 1

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

GCF(51,19,826) x common factors =1 x 1 = 1

LCM(51,19,826) = ( 51 × 19 × 826 ) / 1

LCM(51,19,826) = 800394 / 1

LCM(51,19,826) = 800394
