Greatest Common Factor
We found the factors 430,910 . The biggest common factor number is the GCF number.
So the greatest common factor 430,910 is 10.
Lets's calculate LCM of 485,231
Given numbers has no common factors except 1. So, there LCM is their product i.e 112035
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/112035
Therefore, the GCF of Fractions 430/485,910/231 is 10/112035
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 485,231 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(485,231) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(485,231) x common factors =1 x 1 = 1
LCM(485,231) = ( 485 × 231 ) / 1
LCM(485,231) = 112035 / 1
LCM(485,231) = 112035
