Lets's calculate LCM of 916,661
Given numbers has no common factors except 1. So, there LCM is their product i.e 605476
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/605476
Therefore, the GCF of Fractions 686/916,165/661 is 1/605476
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 916,661 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(916,661) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(916,661) x common factors =1 x 1 = 1
LCM(916,661) = ( 916 × 661 ) / 1
LCM(916,661) = 605476 / 1
LCM(916,661) = 605476
