Lets's calculate LCM of 872,499
Given numbers has no common factors except 1. So, there LCM is their product i.e 435128
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/435128
Therefore, the GCF of Fractions 285/872,579/499 is 3/435128
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 872,499 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(872,499) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(872,499) x common factors =1 x 1 = 1
LCM(872,499) = ( 872 × 499 ) / 1
LCM(872,499) = 435128 / 1
LCM(872,499) = 435128
