Lets's calculate LCM of 35,2304

Given numbers has no common factors except 1. So, there LCM is their product i.e 80640

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 30/80640

Therefore, the GCF of Fractions 810/35,390/2304 is 30/80640

Least Common Multiple of 35,2304 with GCF Formula

Least Common Multiple of 35,2304 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 35,2304 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(35,2304) = 1

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

GCF(35,2304) x common factors =1 x 1 = 1

LCM(35,2304) = ( 35 × 2304 ) / 1

LCM(35,2304) = 80640 / 1

LCM(35,2304) = 80640
