Lets's calculate LCM of 688,729
Given numbers has no common factors except 1. So, there LCM is their product i.e 501552
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/501552
Therefore, the GCF of Fractions 267/688,561/729 is 3/501552
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 688,729 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(688,729) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(688,729) x common factors =1 x 1 = 1
LCM(688,729) = ( 688 × 729 ) / 1
LCM(688,729) = 501552 / 1
LCM(688,729) = 501552
