Greatest Common Factor
We found the factors 9711,9891 . The biggest common factor number is the GCF number.
So the greatest common factor 9711,9891 is 9.
Lets's calculate LCM of 28,711
Given numbers has no common factors except 1. So, there LCM is their product i.e 19908
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/19908
Therefore, the GCF of Fractions 9711/28,9891/711 is 9/19908
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 28,711 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,711) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(28,711) x common factors =1 x 1 = 1
LCM(28,711) = ( 28 × 711 ) / 1
LCM(28,711) = 19908 / 1
LCM(28,711) = 19908
