Greatest Common Factor
We found the factors 989,4485 . The biggest common factor number is the GCF number.
So the greatest common factor 989,4485 is 23.
Lets's calculate LCM of 289,881
Given numbers has no common factors except 1. So, there LCM is their product i.e 254609
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 23/254609
Therefore, the GCF of Fractions 989/289,4485/881 is 23/254609
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 289,881 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(289,881) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(289,881) x common factors =1 x 1 = 1
LCM(289,881) = ( 289 × 881 ) / 1
LCM(289,881) = 254609 / 1
LCM(289,881) = 254609
Here are some samples of GCF of Fractions calculations.
