So the greatest common factor 481,489 is 1.
Lets's calculate LCM of 267,480
3 | 267, 480 |
89, 160 |
∴ So the LCM of the given numbers is 3 x 89 x 160 = 42720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/42720
Therefore, the GCF of Fractions 481/267,489/480 is 1/42720
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 267,480 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(267,480) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(267,480) x common factors =3 x 1 = 3
LCM(267,480) = ( 267 × 480 ) / 3
LCM(267,480) = 128160 / 3
LCM(267,480) = 42720
