So the greatest common factor 91,91,806 is 13.
Lets's calculate LCM of 826,215,561
Given numbers has no common factors except 1. So, there LCM is their product i.e 99627990
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/99627990
Therefore, the GCF of Fractions 91/826,91/215,806/561 is 13/99627990
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 826,215,561 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(826,215,561) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(826,215,561) x common factors =1 x 1 = 1
LCM(826,215,561) = ( 826 × 215 × 561 ) / 1
LCM(826,215,561) = 99627990 / 1
LCM(826,215,561) = 99627990
