Greatest Common Factor
We found the factors 30,519,245 . The biggest common factor number is the GCF number.
So the greatest common factor 30,519,245 is 1.
Lets's calculate LCM of 69,81,648
3 | 69, 81, 648 |
3 | 23, 27, 216 |
3 | 23, 9, 72 |
3 | 23, 3, 24 |
23, 1, 8 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 3 x 23 x 1 x 8 = 14904
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/14904
Therefore, the GCF of Fractions 30/69,519/81,245/648 is 1/14904
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 69,81,648 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,81,648) = 3
common factors(in case of two or more numbers have common factors) = 81
GCF(69,81,648) x common factors =3 x 81 = 243
LCM(69,81,648) = ( 69 × 81 × 648 ) / 243
LCM(69,81,648) = 3621672 / 243
LCM(69,81,648) = 14904
