Lets's calculate LCM of 677,578
Given numbers has no common factors except 1. So, there LCM is their product i.e 391306
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/391306
Therefore, the GCF of Fractions 782/677,855/578 is 1/391306
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 677,578 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(677,578) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(677,578) x common factors =1 x 1 = 1
LCM(677,578) = ( 677 × 578 ) / 1
LCM(677,578) = 391306 / 1
LCM(677,578) = 391306
