:1,2,4,5,8,10,16,20,29,32,40,58,80,116,145,160,232,290,464,580,928,1160,2320,4640
Greatest Common Factor
We found the factors 7910,4640 . The biggest common factor number is the GCF number.
So the greatest common factor 7910,4640 is 10.
Lets's calculate LCM of 811,680
Given numbers has no common factors except 1. So, there LCM is their product i.e 551480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/551480
Therefore, the GCF of Fractions 7910/811,4640/680 is 10/551480
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 811,680 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(811,680) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(811,680) x common factors =1 x 1 = 1
LCM(811,680) = ( 811 × 680 ) / 1
LCM(811,680) = 551480 / 1
LCM(811,680) = 551480
