Lets's calculate LCM of 693,853
Given numbers has no common factors except 1. So, there LCM is their product i.e 591129
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/591129
Therefore, the GCF of Fractions 715/693,208/853 is 13/591129
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 693,853 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(693,853) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(693,853) x common factors =1 x 1 = 1
LCM(693,853) = ( 693 × 853 ) / 1
LCM(693,853) = 591129 / 1
LCM(693,853) = 591129
