Lets's calculate LCM of 255,161

Given numbers has no common factors except 1. So, there LCM is their product i.e 41055

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/41055

Therefore, the GCF of Fractions 72/255,130/161 is 2/41055

Least Common Multiple of 255,161 with GCF Formula

Least Common Multiple of 255,161 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 255,161 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(255,161) = 1

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

GCF(255,161) x common factors =1 x 1 = 1

LCM(255,161) = ( 255 × 161 ) / 1

LCM(255,161) = 41055 / 1

LCM(255,161) = 41055
