Greatest Common Factor
We found the factors 273,905 . The biggest common factor number is the GCF number.
So the greatest common factor 273,905 is 1.
Lets's calculate LCM of 280,209
Given numbers has no common factors except 1. So, there LCM is their product i.e 58520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/58520
Therefore, the GCF of Fractions 273/280,905/209 is 1/58520
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 280,209 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(280,209) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(280,209) x common factors =1 x 1 = 1
LCM(280,209) = ( 280 × 209 ) / 1
LCM(280,209) = 58520 / 1
LCM(280,209) = 58520
