Lets's calculate LCM of 51,1280

Given numbers has no common factors except 1. So, there LCM is their product i.e 65280

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/65280

Therefore, the GCF of Fractions 742/51,830/1280 is 2/65280

Least Common Multiple of 51,1280 with GCF Formula

Least Common Multiple of 51,1280 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 51,1280 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(51,1280) = 1

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

GCF(51,1280) x common factors =1 x 1 = 1

LCM(51,1280) = ( 51 × 1280 ) / 1

LCM(51,1280) = 65280 / 1

LCM(51,1280) = 65280
