Greatest Common Factor
We found the factors 485,139 . The biggest common factor number is the GCF number.
So the greatest common factor 485,139 is 1.
Lets's calculate LCM of 218,103
Given numbers has no common factors except 1. So, there LCM is their product i.e 22454
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/22454
Therefore, the GCF of Fractions 485/218,139/103 is 1/22454
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 218,103 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(218,103) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(218,103) x common factors =1 x 1 = 1
LCM(218,103) = ( 218 × 103 ) / 1
LCM(218,103) = 22454 / 1
LCM(218,103) = 22454
