So the greatest common factor 42,85,416 is 1.
Lets's calculate LCM of 823,532,815
Given numbers has no common factors except 1. So, there LCM is their product i.e 356836340
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/356836340
Therefore, the GCF of Fractions 42/823,85/532,416/815 is 1/356836340
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 823,532,815 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(823,532,815) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(823,532,815) x common factors =1 x 1 = 1
LCM(823,532,815) = ( 823 × 532 × 815 ) / 1
LCM(823,532,815) = 356836340 / 1
LCM(823,532,815) = 356836340
