Lets's calculate LCM of 838,769,973
Given numbers has no common factors except 1. So, there LCM is their product i.e 627022606
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/627022606
Therefore, the GCF of Fractions 65/838,630/769,678/973 is 1/627022606
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 838,769,973 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(838,769,973) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(838,769,973) x common factors =1 x 1 = 1
LCM(838,769,973) = ( 838 × 769 × 973 ) / 1
LCM(838,769,973) = 627022606 / 1
LCM(838,769,973) = 627022606
