We found the factors 211,398 . The biggest common factor number is the GCF number.
So the greatest common factor 211,398 is 1.
Lets's calculate LCM of 78,403
13 | 78, 403 |
6, 31 |
∴ So the LCM of the given numbers is 13 x 6 x 31 = 2418
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2418
Therefore, the GCF of Fractions 211/78,398/403 is 1/2418
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 78,403 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,403) = 13
common factors(in case of two or more numbers have common factors) = 1
GCF(78,403) x common factors =13 x 1 = 13
LCM(78,403) = ( 78 × 403 ) / 13
LCM(78,403) = 31434 / 13
LCM(78,403) = 2418
