Lets's calculate LCM of 277,281
Given numbers has no common factors except 1. So, there LCM is their product i.e 77837
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 109/77837
Therefore, the GCF of Fractions 872/277,981/281 is 109/77837
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 277,281 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(277,281) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(277,281) x common factors =1 x 1 = 1
LCM(277,281) = ( 277 × 281 ) / 1
LCM(277,281) = 77837 / 1
LCM(277,281) = 77837
