Greatest Common Factor
We found the factors 854,491 . The biggest common factor number is the GCF number.
So the greatest common factor 854,491 is 1.
Lets's calculate LCM of 857,411
Given numbers has no common factors except 1. So, there LCM is their product i.e 352227
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/352227
Therefore, the GCF of Fractions 854/857,491/411 is 1/352227
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 857,411 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(857,411) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(857,411) x common factors =1 x 1 = 1
LCM(857,411) = ( 857 × 411 ) / 1
LCM(857,411) = 352227 / 1
LCM(857,411) = 352227
