Lets's calculate LCM of 353,108

Given numbers has no common factors except 1. So, there LCM is their product i.e 38124

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 27/38124

Therefore, the GCF of Fractions 81/353,297/108 is 27/38124

Least Common Multiple of 353,108 with GCF Formula

Least Common Multiple of 353,108 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 353,108 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(353,108) = 1

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

GCF(353,108) x common factors =1 x 1 = 1

LCM(353,108) = ( 353 × 108 ) / 1

LCM(353,108) = 38124 / 1

LCM(353,108) = 38124
