Lets's calculate LCM of 168,7201

Given numbers has no common factors except 1. So, there LCM is their product i.e 1209768

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 27/1209768

Therefore, the GCF of Fractions 54/168,81/7201 is 27/1209768

Least Common Multiple of 168,7201 with GCF Formula

Least Common Multiple of 168,7201 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 168,7201 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(168,7201) = 1

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

GCF(168,7201) x common factors =1 x 1 = 1

LCM(168,7201) = ( 168 × 7201 ) / 1

LCM(168,7201) = 1209768 / 1

LCM(168,7201) = 1209768
