So the greatest common factor 87,91,657 is 1.
Lets's calculate LCM of 573,746,161
Given numbers has no common factors except 1. So, there LCM is their product i.e 68820738
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/68820738
Therefore, the GCF of Fractions 87/573,91/746,657/161 is 1/68820738
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 573,746,161 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(573,746,161) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(573,746,161) x common factors =1 x 1 = 1
LCM(573,746,161) = ( 573 × 746 × 161 ) / 1
LCM(573,746,161) = 68820738 / 1
LCM(573,746,161) = 68820738
