Lets's calculate LCM of 768,459
3 | 768, 459 |
256, 153 |
∴ So the LCM of the given numbers is 3 x 256 x 153 = 117504
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/117504
Therefore, the GCF of Fractions 745/768,555/459 is 5/117504
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 768,459 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(768,459) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(768,459) x common factors =3 x 1 = 3
LCM(768,459) = ( 768 × 459 ) / 3
LCM(768,459) = 352512 / 3
LCM(768,459) = 117504
