So the greatest common factor 234,680 is 2.
Lets's calculate LCM of 665,811
Given numbers has no common factors except 1. So, there LCM is their product i.e 539315
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/539315
Therefore, the GCF of Fractions 234/665,680/811 is 2/539315
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 665,811 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(665,811) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(665,811) x common factors =1 x 1 = 1
LCM(665,811) = ( 665 × 811 ) / 1
LCM(665,811) = 539315 / 1
LCM(665,811) = 539315
