Lets's calculate LCM of 286,617
Given numbers has no common factors except 1. So, there LCM is their product i.e 176462
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/176462
Therefore, the GCF of Fractions 868/286,408/617 is 4/176462
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 286,617 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(286,617) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(286,617) x common factors =1 x 1 = 1
LCM(286,617) = ( 286 × 617 ) / 1
LCM(286,617) = 176462 / 1
LCM(286,617) = 176462
