So the greatest common factor 72,98,805 is 1.
Lets's calculate LCM of 89,457,843
Given numbers has no common factors except 1. So, there LCM is their product i.e 34287339
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/34287339
Therefore, the GCF of Fractions 72/89,98/457,805/843 is 1/34287339
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 89,457,843 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,457,843) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,457,843) x common factors =1 x 1 = 1
LCM(89,457,843) = ( 89 × 457 × 843 ) / 1
LCM(89,457,843) = 34287339 / 1
LCM(89,457,843) = 34287339
