So the greatest common factor 17,39,359 is 1.
Lets's calculate LCM of 639,878,941
Given numbers has no common factors except 1. So, there LCM is their product i.e 527940522
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/527940522
Therefore, the GCF of Fractions 17/639,39/878,359/941 is 1/527940522
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 639,878,941 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(639,878,941) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(639,878,941) x common factors =1 x 1 = 1
LCM(639,878,941) = ( 639 × 878 × 941 ) / 1
LCM(639,878,941) = 527940522 / 1
LCM(639,878,941) = 527940522
