Lets's calculate LCM of 733,578
Given numbers has no common factors except 1. So, there LCM is their product i.e 423674
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/423674
Therefore, the GCF of Fractions 505/733,385/578 is 5/423674
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 733,578 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(733,578) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(733,578) x common factors =1 x 1 = 1
LCM(733,578) = ( 733 × 578 ) / 1
LCM(733,578) = 423674 / 1
LCM(733,578) = 423674
