Greatest Common Factor
We found the factors 394,157 . The biggest common factor number is the GCF number.
So the greatest common factor 394,157 is 1.
Lets's calculate LCM of 442,805
Given numbers has no common factors except 1. So, there LCM is their product i.e 355810
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/355810
Therefore, the GCF of Fractions 394/442,157/805 is 1/355810
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 442,805 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(442,805) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(442,805) x common factors =1 x 1 = 1
LCM(442,805) = ( 442 × 805 ) / 1
LCM(442,805) = 355810 / 1
LCM(442,805) = 355810
