Greatest Common Factor
We found the factors 288,9870 . The biggest common factor number is the GCF number.
So the greatest common factor 288,9870 is 6.
Lets's calculate LCM of 243,997
Given numbers has no common factors except 1. So, there LCM is their product i.e 242271
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/242271
Therefore, the GCF of Fractions 288/243,9870/997 is 6/242271
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 243,997 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(243,997) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(243,997) x common factors =1 x 1 = 1
LCM(243,997) = ( 243 × 997 ) / 1
LCM(243,997) = 242271 / 1
LCM(243,997) = 242271
