So the greatest common factor 78,328,354 is 2.
Lets's calculate LCM of 847,449,551
Given numbers has no common factors except 1. So, there LCM is their product i.e 209546953
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/209546953
Therefore, the GCF of Fractions 78/847,328/449,354/551 is 2/209546953
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 847,449,551 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(847,449,551) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(847,449,551) x common factors =1 x 1 = 1
LCM(847,449,551) = ( 847 × 449 × 551 ) / 1
LCM(847,449,551) = 209546953 / 1
LCM(847,449,551) = 209546953
