Therefore, the GCF of Fractions 54/243,972/411,786/355 is 6/11818305
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 243,411,355 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(243,411,355) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(243,411,355) x common factors =1 x 3 = 3
LCM(243,411,355) = ( 243 × 411 × 355 ) / 3
LCM(243,411,355) = 35454915 / 3
LCM(243,411,355) = 11818305
