Greatest Common Factor
We found the factors 842,257 . The biggest common factor number is the GCF number.
So the greatest common factor 842,257 is 1.
Lets's calculate LCM of 871,854
Given numbers has no common factors except 1. So, there LCM is their product i.e 743834
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/743834
Therefore, the GCF of Fractions 842/871,257/854 is 1/743834
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 871,854 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(871,854) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(871,854) x common factors =1 x 1 = 1
LCM(871,854) = ( 871 × 854 ) / 1
LCM(871,854) = 743834 / 1
LCM(871,854) = 743834
