Greatest Common Factor
We found the factors 230,2691 . The biggest common factor number is the GCF number.
So the greatest common factor 230,2691 is 23.
Lets's calculate LCM of 389,535
Given numbers has no common factors except 1. So, there LCM is their product i.e 208115
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 23/208115
Therefore, the GCF of Fractions 230/389,2691/535 is 23/208115
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 389,535 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(389,535) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(389,535) x common factors =1 x 1 = 1
LCM(389,535) = ( 389 × 535 ) / 1
LCM(389,535) = 208115 / 1
LCM(389,535) = 208115
