Greatest Common Factor
We found the factors 34,390,497 . The biggest common factor number is the GCF number.
So the greatest common factor 34,390,497 is 1.
Lets's calculate LCM of 81,41,859
Given numbers has no common factors except 1. So, there LCM is their product i.e 2852739
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2852739
Therefore, the GCF of Fractions 34/81,390/41,497/859 is 1/2852739
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 81,41,859 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,41,859) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,41,859) x common factors =1 x 1 = 1
LCM(81,41,859) = ( 81 × 41 × 859 ) / 1
LCM(81,41,859) = 2852739 / 1
LCM(81,41,859) = 2852739
