Greatest Common Factor
We found the factors 256,671 . The biggest common factor number is the GCF number.
So the greatest common factor 256,671 is 1.
Lets's calculate LCM of 857,212
Given numbers has no common factors except 1. So, there LCM is their product i.e 181684
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/181684
Therefore, the GCF of Fractions 256/857,671/212 is 1/181684
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 857,212 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(857,212) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(857,212) x common factors =1 x 1 = 1
LCM(857,212) = ( 857 × 212 ) / 1
LCM(857,212) = 181684 / 1
LCM(857,212) = 181684
