Greatest Common Factor
We found the factors 683,668 . The biggest common factor number is the GCF number.
So the greatest common factor 683,668 is 1.
Lets's calculate LCM of 478,607
Given numbers has no common factors except 1. So, there LCM is their product i.e 290146
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/290146
Therefore, the GCF of Fractions 683/478,668/607 is 1/290146
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 478,607 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(478,607) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(478,607) x common factors =1 x 1 = 1
LCM(478,607) = ( 478 × 607 ) / 1
LCM(478,607) = 290146 / 1
LCM(478,607) = 290146
