Greatest Common Factor
We found the factors 864,343 . The biggest common factor number is the GCF number.
So the greatest common factor 864,343 is 1.
Lets's calculate LCM of 81,125
Given numbers has no common factors except 1. So, there LCM is their product i.e 10125
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10125
Therefore, the GCF of Fractions 864/81,343/125 is 1/10125
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 81,125 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,125) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,125) x common factors =1 x 1 = 1
LCM(81,125) = ( 81 × 125 ) / 1
LCM(81,125) = 10125 / 1
LCM(81,125) = 10125
