Lets's calculate LCM of 389,685
Given numbers has no common factors except 1. So, there LCM is their product i.e 266465
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/266465
Therefore, the GCF of Fractions 702/389,455/685 is 13/266465
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 389,685 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(389,685) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(389,685) x common factors =1 x 1 = 1
LCM(389,685) = ( 389 × 685 ) / 1
LCM(389,685) = 266465 / 1
LCM(389,685) = 266465
