We found the factors 955,1657 . The biggest common factor number is the GCF number.
So the greatest common factor 955,1657 is 1.
Lets's calculate LCM of 643,899
Given numbers has no common factors except 1. So, there LCM is their product i.e 578057
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/578057
Therefore, the GCF of Fractions 955/643,1657/899 is 1/578057
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 643,899 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(643,899) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(643,899) x common factors =1 x 1 = 1
LCM(643,899) = ( 643 × 899 ) / 1
LCM(643,899) = 578057 / 1
LCM(643,899) = 578057
