So the greatest common factor 23,81,144 is 1.
Lets's calculate LCM of 931,911,317
Given numbers has no common factors except 1. So, there LCM is their product i.e 268860697
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/268860697
Therefore, the GCF of Fractions 23/931,81/911,144/317 is 1/268860697
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 931,911,317 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(931,911,317) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(931,911,317) x common factors =1 x 1 = 1
LCM(931,911,317) = ( 931 × 911 × 317 ) / 1
LCM(931,911,317) = 268860697 / 1
LCM(931,911,317) = 268860697
