Lets's calculate LCM of 529,321
Given numbers has no common factors except 1. So, there LCM is their product i.e 169809
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/169809
Therefore, the GCF of Fractions 138/529,128/321 is 2/169809
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 529,321 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(529,321) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(529,321) x common factors =1 x 1 = 1
LCM(529,321) = ( 529 × 321 ) / 1
LCM(529,321) = 169809 / 1
LCM(529,321) = 169809
