We found the factors 1938,6936 . The biggest common factor number is the GCF number.
So the greatest common factor 1938,6936 is 102.
Lets's calculate LCM of 981,817
Given numbers has no common factors except 1. So, there LCM is their product i.e 801477
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 102/801477
Therefore, the GCF of Fractions 1938/981,6936/817 is 102/801477
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 981,817 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(981,817) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(981,817) x common factors =1 x 1 = 1
LCM(981,817) = ( 981 × 817 ) / 1
LCM(981,817) = 801477 / 1
LCM(981,817) = 801477
