Lets's calculate LCM of 618,870
2 | 618, 870 |
3 | 309, 435 |
103, 145 |
∴ So the LCM of the given numbers is 2 x 3 x 103 x 145 = 89610
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/89610
Therefore, the GCF of Fractions 808/618,417/870 is 1/89610
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 618,870 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(618,870) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(618,870) x common factors =6 x 1 = 6
LCM(618,870) = ( 618 × 870 ) / 6
LCM(618,870) = 537660 / 6
LCM(618,870) = 89610
