Lets's calculate GCF of 86,19
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 618,8428
2 | 618, 8428 |
309, 4214 |
∴ So the LCM of the given numbers is 2 x 309 x 4214 = 2604252
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2604252
Therefore, the GCF of Fractions 86/618,19/8428 is 1/2604252
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 618,8428 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(618,8428) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(618,8428) x common factors =2 x 1 = 2
LCM(618,8428) = ( 618 × 8428 ) / 2
LCM(618,8428) = 5208504 / 2
LCM(618,8428) = 2604252
