Greatest Common Factor
We found the factors 749,305 . The biggest common factor number is the GCF number.
So the greatest common factor 749,305 is 1.
Lets's calculate LCM of 389,885
Given numbers has no common factors except 1. So, there LCM is their product i.e 344265
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/344265
Therefore, the GCF of Fractions 749/389,305/885 is 1/344265
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 389,885 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(389,885) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(389,885) x common factors =1 x 1 = 1
LCM(389,885) = ( 389 × 885 ) / 1
LCM(389,885) = 344265 / 1
LCM(389,885) = 344265
