So the greatest common factor 660,9345 is 15.
Lets's calculate LCM of 811,913
Given numbers has no common factors except 1. So, there LCM is their product i.e 740443
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/740443
Therefore, the GCF of Fractions 660/811,9345/913 is 15/740443
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 811,913 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(811,913) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(811,913) x common factors =1 x 1 = 1
LCM(811,913) = ( 811 × 913 ) / 1
LCM(811,913) = 740443 / 1
LCM(811,913) = 740443
