Lets's calculate LCM of 107,8606
Given numbers has no common factors except 1. So, there LCM is their product i.e 920842
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/920842
Therefore, the GCF of Fractions 85/107,1972/8606 is 17/920842
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 107,8606 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(107,8606) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(107,8606) x common factors =1 x 1 = 1
LCM(107,8606) = ( 107 × 8606 ) / 1
LCM(107,8606) = 920842 / 1
LCM(107,8606) = 920842
