So the greatest common factor 551,280 is 1.
Lets's calculate LCM of 545,691
Given numbers has no common factors except 1. So, there LCM is their product i.e 376595
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/376595
Therefore, the GCF of Fractions 551/545,280/691 is 1/376595
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 545,691 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(545,691) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(545,691) x common factors =1 x 1 = 1
LCM(545,691) = ( 545 × 691 ) / 1
LCM(545,691) = 376595 / 1
LCM(545,691) = 376595
