Greatest Common Factor
We found the factors 413,428 . The biggest common factor number is the GCF number.
So the greatest common factor 413,428 is 1.
Lets's calculate LCM of 389,917
Given numbers has no common factors except 1. So, there LCM is their product i.e 356713
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/356713
Therefore, the GCF of Fractions 413/389,428/917 is 1/356713
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 389,917 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(389,917) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(389,917) x common factors =1 x 1 = 1
LCM(389,917) = ( 389 × 917 ) / 1
LCM(389,917) = 356713 / 1
LCM(389,917) = 356713
