So the greatest common factor 8,40,21,818 is 1.
Lets's calculate LCM of 39,37,890,427
Given numbers has no common factors except 1. So, there LCM is their product i.e 548383290
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/548383290
Therefore, the GCF of Fractions 8/39,40/37,21/890,818/427 is 1/548383290
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 39,37,890,427 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,37,890,427) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(39,37,890,427) x common factors =1 x 1 = 1
LCM(39,37,890,427) = ( 39 × 37 × 890 × 427 ) / 1
LCM(39,37,890,427) = 548383290 / 1
LCM(39,37,890,427) = 548383290
