Greatest Common Factor
We found the factors 786,456 . The biggest common factor number is the GCF number.
So the greatest common factor 786,456 is 6.
Lets's calculate LCM of 843,940
Given numbers has no common factors except 1. So, there LCM is their product i.e 792420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/792420
Therefore, the GCF of Fractions 786/843,456/940 is 6/792420
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 843,940 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(843,940) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(843,940) x common factors =1 x 1 = 1
LCM(843,940) = ( 843 × 940 ) / 1
LCM(843,940) = 792420 / 1
LCM(843,940) = 792420
