Greatest Common Factor
We found the factors 342,1653 . The biggest common factor number is the GCF number.
So the greatest common factor 342,1653 is 57.
Lets's calculate LCM of 243,881
Given numbers has no common factors except 1. So, there LCM is their product i.e 214083
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 57/214083
Therefore, the GCF of Fractions 342/243,1653/881 is 57/214083
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 243,881 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(243,881) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(243,881) x common factors =1 x 1 = 1
LCM(243,881) = ( 243 × 881 ) / 1
LCM(243,881) = 214083 / 1
LCM(243,881) = 214083
