Greatest Common Factor
We found the factors 3920,7811 . The biggest common factor number is the GCF number.
So the greatest common factor 3920,7811 is 1.
Lets's calculate LCM of 401,1666
Given numbers has no common factors except 1. So, there LCM is their product i.e 668066
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/668066
Therefore, the GCF of Fractions 3920/401,7811/1666 is 1/668066
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 401,1666 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(401,1666) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(401,1666) x common factors =1 x 1 = 1
LCM(401,1666) = ( 401 × 1666 ) / 1
LCM(401,1666) = 668066 / 1
LCM(401,1666) = 668066
