Greatest Common Factor
We found the factors 432,891 . The biggest common factor number is the GCF number.
So the greatest common factor 432,891 is 27.
Lets's calculate LCM of 905,711
Given numbers has no common factors except 1. So, there LCM is their product i.e 643455
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 27/643455
Therefore, the GCF of Fractions 432/905,891/711 is 27/643455
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 905,711 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(905,711) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(905,711) x common factors =1 x 1 = 1
LCM(905,711) = ( 905 × 711 ) / 1
LCM(905,711) = 643455 / 1
LCM(905,711) = 643455
