Lets's calculate LCM of 38,41,407

Given numbers has no common factors except 1. So, there LCM is their product i.e 634106

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/634106

Therefore, the GCF of Fractions 20/38,82/41,154/407 is 2/634106

Least Common Multiple of 38,41,407 with GCF Formula

Least Common Multiple of 38,41,407 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 38,41,407 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(38,41,407) = 1

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

GCF(38,41,407) x common factors =1 x 1 = 1

LCM(38,41,407) = ( 38 × 41 × 407 ) / 1

LCM(38,41,407) = 634106 / 1

LCM(38,41,407) = 634106
