So the greatest common factor 86,798,447 is 1.
Lets's calculate LCM of 79,65,851
Given numbers has no common factors except 1. So, there LCM is their product i.e 4369885
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4369885
Therefore, the GCF of Fractions 86/79,798/65,447/851 is 1/4369885
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 79,65,851 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,65,851) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,65,851) x common factors =1 x 1 = 1
LCM(79,65,851) = ( 79 × 65 × 851 ) / 1
LCM(79,65,851) = 4369885 / 1
LCM(79,65,851) = 4369885
