Greatest Common Factor
We found the factors 305,797 . The biggest common factor number is the GCF number.
So the greatest common factor 305,797 is 1.
Lets's calculate LCM of 428,949
Given numbers has no common factors except 1. So, there LCM is their product i.e 406172
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/406172
Therefore, the GCF of Fractions 305/428,797/949 is 1/406172
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 428,949 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(428,949) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(428,949) x common factors =1 x 1 = 1
LCM(428,949) = ( 428 × 949 ) / 1
LCM(428,949) = 406172 / 1
LCM(428,949) = 406172
