Greatest Common Factor
We found the factors 539,731 . The biggest common factor number is the GCF number.
So the greatest common factor 539,731 is 1.
Lets's calculate LCM of 645,871
Given numbers has no common factors except 1. So, there LCM is their product i.e 561795
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/561795
Therefore, the GCF of Fractions 539/645,731/871 is 1/561795
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 645,871 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(645,871) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(645,871) x common factors =1 x 1 = 1
LCM(645,871) = ( 645 × 871 ) / 1
LCM(645,871) = 561795 / 1
LCM(645,871) = 561795
