So the greatest common factor 67,20,105 is 1.
Lets's calculate LCM of 803,985,269
Given numbers has no common factors except 1. So, there LCM is their product i.e 212766895
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/212766895
Therefore, the GCF of Fractions 67/803,20/985,105/269 is 1/212766895
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 803,985,269 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(803,985,269) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(803,985,269) x common factors =1 x 1 = 1
LCM(803,985,269) = ( 803 × 985 × 269 ) / 1
LCM(803,985,269) = 212766895 / 1
LCM(803,985,269) = 212766895
