So the greatest common factor 682,640 is 2.
Lets's calculate LCM of 20,1131
Given numbers has no common factors except 1. So, there LCM is their product i.e 22620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/22620
Therefore, the GCF of Fractions 682/20,640/1131 is 2/22620
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 20,1131 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,1131) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(20,1131) x common factors =1 x 1 = 1
LCM(20,1131) = ( 20 × 1131 ) / 1
LCM(20,1131) = 22620 / 1
LCM(20,1131) = 22620
