Lets's calculate LCM of 51,31,517

Given numbers has no common factors except 1. So, there LCM is their product i.e 817377

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/817377

Therefore, the GCF of Fractions 20/51,202/31,298/517 is 2/817377

Least Common Multiple of 51,31,517 with GCF Formula

Least Common Multiple of 51,31,517 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 51,31,517 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(51,31,517) = 1

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

GCF(51,31,517) x common factors =1 x 1 = 1

LCM(51,31,517) = ( 51 × 31 × 517 ) / 1

LCM(51,31,517) = 817377 / 1

LCM(51,31,517) = 817377
