So the greatest common factor 97,57,880 is 1.
Lets's calculate LCM of 459,420,427
3 | 459, 420, 427 |
7 | 153, 140, 427 |
153, 20, 61 |
∴ So the LCM of the given numbers is 3 x 7 x 153 x 20 x 61 = 3919860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3919860
Therefore, the GCF of Fractions 97/459,57/420,880/427 is 1/3919860
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 459,420,427 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(459,420,427) = 1
common factors(in case of two or more numbers have common factors) = 21
GCF(459,420,427) x common factors =1 x 21 = 21
LCM(459,420,427) = ( 459 × 420 × 427 ) / 21
LCM(459,420,427) = 82317060 / 21
LCM(459,420,427) = 3919860
