So the greatest common factor 77,83,402 is 1.
Lets's calculate LCM of 793,833,139
Given numbers has no common factors except 1. So, there LCM is their product i.e 91819091
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/91819091
Therefore, the GCF of Fractions 77/793,83/833,402/139 is 1/91819091
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 793,833,139 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(793,833,139) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(793,833,139) x common factors =1 x 1 = 1
LCM(793,833,139) = ( 793 × 833 × 139 ) / 1
LCM(793,833,139) = 91819091 / 1
LCM(793,833,139) = 91819091
