:1,2,4,5,7,8,10,14,16,20,28,35,40,49,56,70,80,98,112,140,196,245,280,392,490,560,784,980,1960,3920
Greatest Common Factor
We found the factors 1388,3920 . The biggest common factor number is the GCF number.
So the greatest common factor 1388,3920 is 4.
Lets's calculate LCM of 281,501
Given numbers has no common factors except 1. So, there LCM is their product i.e 140781
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/140781
Therefore, the GCF of Fractions 1388/281,3920/501 is 4/140781
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 281,501 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(281,501) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(281,501) x common factors =1 x 1 = 1
LCM(281,501) = ( 281 × 501 ) / 1
LCM(281,501) = 140781 / 1
LCM(281,501) = 140781
