Greatest Common Factor
We found the factors 998,397 . The biggest common factor number is the GCF number.
So the greatest common factor 998,397 is 1.
Lets's calculate LCM of 649,618
Given numbers has no common factors except 1. So, there LCM is their product i.e 401082
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/401082
Therefore, the GCF of Fractions 998/649,397/618 is 1/401082
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 649,618 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(649,618) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(649,618) x common factors =1 x 1 = 1
LCM(649,618) = ( 649 × 618 ) / 1
LCM(649,618) = 401082 / 1
LCM(649,618) = 401082
