We found the factors 19,13,958 . The biggest common factor number is the GCF number.
So the greatest common factor 19,13,958 is 1.
Lets's calculate LCM of 392,157,309
Given numbers has no common factors except 1. So, there LCM is their product i.e 19017096
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19017096
Therefore, the GCF of Fractions 19/392,13/157,958/309 is 1/19017096
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 392,157,309 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(392,157,309) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(392,157,309) x common factors =1 x 1 = 1
LCM(392,157,309) = ( 392 × 157 × 309 ) / 1
LCM(392,157,309) = 19017096 / 1
LCM(392,157,309) = 19017096
