Greatest Common Factor
We found the factors 30,84,286 . The biggest common factor number is the GCF number.
So the greatest common factor 30,84,286 is 2.
Lets's calculate LCM of 428,813,805
Given numbers has no common factors except 1. So, there LCM is their product i.e 280111020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/280111020
Therefore, the GCF of Fractions 30/428,84/813,286/805 is 2/280111020
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 428,813,805 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(428,813,805) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(428,813,805) x common factors =1 x 1 = 1
LCM(428,813,805) = ( 428 × 813 × 805 ) / 1
LCM(428,813,805) = 280111020 / 1
LCM(428,813,805) = 280111020
