So the greatest common factor 75,69,245 is 1.
Lets's calculate LCM of 815,142,891
Given numbers has no common factors except 1. So, there LCM is their product i.e 103115430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/103115430
Therefore, the GCF of Fractions 75/815,69/142,245/891 is 1/103115430
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 815,142,891 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(815,142,891) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(815,142,891) x common factors =1 x 1 = 1
LCM(815,142,891) = ( 815 × 142 × 891 ) / 1
LCM(815,142,891) = 103115430 / 1
LCM(815,142,891) = 103115430
