So the greatest common factor 45,30,645 is 15.
Lets's calculate LCM of 746,855,968
2 | 746, 855, 968 |
373, 855, 484 |
∴ So the LCM of the given numbers is 2 x 373 x 855 x 484 = 308709720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/308709720
Therefore, the GCF of Fractions 45/746,30/855,645/968 is 15/308709720
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 746,855,968 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(746,855,968) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(746,855,968) x common factors =1 x 2 = 2
LCM(746,855,968) = ( 746 × 855 × 968 ) / 2
LCM(746,855,968) = 617419440 / 2
LCM(746,855,968) = 308709720
