Lets's calculate LCM of 663,209
Given numbers has no common factors except 1. So, there LCM is their product i.e 138567
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/138567
Therefore, the GCF of Fractions 486/663,620/209 is 2/138567
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 663,209 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(663,209) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(663,209) x common factors =1 x 1 = 1
LCM(663,209) = ( 663 × 209 ) / 1
LCM(663,209) = 138567 / 1
LCM(663,209) = 138567
