Greatest Common Factor
We found the factors 86,84,20 . The biggest common factor number is the GCF number.
So the greatest common factor 86,84,20 is 2.
Lets's calculate LCM of 48,71,919
Given numbers has no common factors except 1. So, there LCM is their product i.e 3131952
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/3131952
Therefore, the GCF of Fractions 86/48,84/71,20/919 is 2/3131952
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 48,71,919 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(48,71,919) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(48,71,919) x common factors =1 x 1 = 1
LCM(48,71,919) = ( 48 × 71 × 919 ) / 1
LCM(48,71,919) = 3131952 / 1
LCM(48,71,919) = 3131952
