Greatest Common Factor
We found the factors 494,918 . The biggest common factor number is the GCF number.
So the greatest common factor 494,918 is 2.
Lets's calculate LCM of 685,904
Given numbers has no common factors except 1. So, there LCM is their product i.e 619240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/619240
Therefore, the GCF of Fractions 494/685,918/904 is 2/619240
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 685,904 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(685,904) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(685,904) x common factors =1 x 1 = 1
LCM(685,904) = ( 685 × 904 ) / 1
LCM(685,904) = 619240 / 1
LCM(685,904) = 619240
