So the greatest common factor 743,645 is 1.
Lets's calculate LCM of 666,599
Given numbers has no common factors except 1. So, there LCM is their product i.e 398934
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/398934
Therefore, the GCF of Fractions 743/666,645/599 is 1/398934
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 666,599 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(666,599) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(666,599) x common factors =1 x 1 = 1
LCM(666,599) = ( 666 × 599 ) / 1
LCM(666,599) = 398934 / 1
LCM(666,599) = 398934
