So the greatest common factor 640,714 is 2.
Lets's calculate LCM of 505,369
Given numbers has no common factors except 1. So, there LCM is their product i.e 186345
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/186345
Therefore, the GCF of Fractions 640/505,714/369 is 2/186345
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 505,369 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(505,369) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(505,369) x common factors =1 x 1 = 1
LCM(505,369) = ( 505 × 369 ) / 1
LCM(505,369) = 186345 / 1
LCM(505,369) = 186345
