Greatest Common Factor
We found the factors 813,634 . The biggest common factor number is the GCF number.
So the greatest common factor 813,634 is 1.
Lets's calculate LCM of 867,473
Given numbers has no common factors except 1. So, there LCM is their product i.e 410091
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/410091
Therefore, the GCF of Fractions 813/867,634/473 is 1/410091
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 867,473 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(867,473) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(867,473) x common factors =1 x 1 = 1
LCM(867,473) = ( 867 × 473 ) / 1
LCM(867,473) = 410091 / 1
LCM(867,473) = 410091
