Lets's calculate LCM of 42,181

Given numbers has no common factors except 1. So, there LCM is their product i.e 7602

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 414/7602

Therefore, the GCF of Fractions 1656/42,2070/181 is 414/7602

Least Common Multiple of 42,181 with GCF Formula

Least Common Multiple of 42,181 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 42,181 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,181) = 1

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

GCF(42,181) x common factors =1 x 1 = 1

LCM(42,181) = ( 42 × 181 ) / 1

LCM(42,181) = 7602 / 1

LCM(42,181) = 7602
