Lets's calculate LCM of 805,979
Given numbers has no common factors except 1. So, there LCM is their product i.e 788095
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/788095
Therefore, the GCF of Fractions 773/805,855/979 is 1/788095
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 805,979 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(805,979) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(805,979) x common factors =1 x 1 = 1
LCM(805,979) = ( 805 × 979 ) / 1
LCM(805,979) = 788095 / 1
LCM(805,979) = 788095
