Greatest Common Factor
We found the factors 225,9855 . The biggest common factor number is the GCF number.
So the greatest common factor 225,9855 is 45.
Lets's calculate LCM of 261,931
Given numbers has no common factors except 1. So, there LCM is their product i.e 242991
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 45/242991
Therefore, the GCF of Fractions 225/261,9855/931 is 45/242991
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 261,931 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(261,931) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(261,931) x common factors =1 x 1 = 1
LCM(261,931) = ( 261 × 931 ) / 1
LCM(261,931) = 242991 / 1
LCM(261,931) = 242991
