:1,389
Greatest Common Factor
We found the factors 711,389 . The biggest common factor number is the GCF number.
So the greatest common factor 711,389 is 1.
Lets's calculate LCM of 278,843
Given numbers has no common factors except 1. So, there LCM is their product i.e 234354
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/234354
Therefore, the GCF of Fractions 711/278,389/843 is 1/234354
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 278,843 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(278,843) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(278,843) x common factors =1 x 1 = 1
LCM(278,843) = ( 278 × 843 ) / 1
LCM(278,843) = 234354 / 1
LCM(278,843) = 234354
