So the greatest common factor 99,804,688 is 1.
Lets's calculate LCM of 78,47,317
Given numbers has no common factors except 1. So, there LCM is their product i.e 1162122
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1162122
Therefore, the GCF of Fractions 99/78,804/47,688/317 is 1/1162122
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 78,47,317 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,47,317) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(78,47,317) x common factors =1 x 1 = 1
LCM(78,47,317) = ( 78 × 47 × 317 ) / 1
LCM(78,47,317) = 1162122 / 1
LCM(78,47,317) = 1162122
