Greatest Common Factor
We found the factors 897,438 . The biggest common factor number is the GCF number.
So the greatest common factor 897,438 is 3.
Lets's calculate LCM of 83,359
Given numbers has no common factors except 1. So, there LCM is their product i.e 29797
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/29797
Therefore, the GCF of Fractions 897/83,438/359 is 3/29797
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 83,359 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(83,359) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(83,359) x common factors =1 x 1 = 1
LCM(83,359) = ( 83 × 359 ) / 1
LCM(83,359) = 29797 / 1
LCM(83,359) = 29797
