Greatest Common Factor
We found the factors 641,398 . The biggest common factor number is the GCF number.
So the greatest common factor 641,398 is 1.
Lets's calculate LCM of 683,386
Given numbers has no common factors except 1. So, there LCM is their product i.e 263638
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/263638
Therefore, the GCF of Fractions 641/683,398/386 is 1/263638
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 683,386 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(683,386) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(683,386) x common factors =1 x 1 = 1
LCM(683,386) = ( 683 × 386 ) / 1
LCM(683,386) = 263638 / 1
LCM(683,386) = 263638
