Lets's calculate LCM of 599,440,641
Given numbers has no common factors except 1. So, there LCM is their product i.e 168941960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/168941960
Therefore, the GCF of Fractions 40/599,74/440,768/641 is 2/168941960
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 599,440,641 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(599,440,641) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(599,440,641) x common factors =1 x 1 = 1
LCM(599,440,641) = ( 599 × 440 × 641 ) / 1
LCM(599,440,641) = 168941960 / 1
LCM(599,440,641) = 168941960
