1,3,9,27,73,219,657,1971
Greatest Common Factor
We found the factors 4290,1971 . The biggest common factor number is the GCF number.
So the greatest common factor 4290,1971 is 3.
Lets's calculate LCM of 389,140
Given numbers has no common factors except 1. So, there LCM is their product i.e 54460
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/54460
Therefore, the GCF of Fractions 4290/389,1971/140 is 3/54460
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 389,140 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(389,140) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(389,140) x common factors =1 x 1 = 1
LCM(389,140) = ( 389 × 140 ) / 1
LCM(389,140) = 54460 / 1
LCM(389,140) = 54460
