GCF of Denominators means GCF of 81,18,361 as per the given fractions.

GCF of 81,18,361 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 165,389,331

LCM of Fractions 165/81,389/18,331/361 is 21245235

Given numbers has no common factors except 1. So, there LCM is their product i.e 21245235

Least Common Multiple of 165,389,331 with GCF Formula

Least Common Multiple of 165,389,331 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 165,389,331 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(165,389,331) = 1

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

GCF(165,389,331) x common factors =1 x 1 = 1

LCM(165,389,331) = ( 165 × 389 × 331 ) / 1

LCM(165,389,331) = 21245235 / 1

LCM(165,389,331) = 21245235


Lets's calculate GCF of 81,18,361

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 21245235/1

Therefore the LCM of Fractions 165/81,389/18,331/361 is 21245235
