Lets's calculate LCM of 436,589,843
Given numbers has no common factors except 1. So, there LCM is their product i.e 216485772
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/216485772
Therefore, the GCF of Fractions 98/436,21/589,580/843 is 1/216485772
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 436,589,843 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(436,589,843) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(436,589,843) x common factors =1 x 1 = 1
LCM(436,589,843) = ( 436 × 589 × 843 ) / 1
LCM(436,589,843) = 216485772 / 1
LCM(436,589,843) = 216485772
