Lets's calculate LCM of 945,665
5 | 945, 665 |
7 | 189, 133 |
27, 19 |
∴ So the LCM of the given numbers is 5 x 7 x 27 x 19 = 17955
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/17955
Therefore, the GCF of Fractions 999/945,642/665 is 3/17955
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 945,665 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(945,665) = 35
common factors(in case of two or more numbers have common factors) = 1
GCF(945,665) x common factors =35 x 1 = 35
LCM(945,665) = ( 945 × 665 ) / 35
LCM(945,665) = 628425 / 35
LCM(945,665) = 17955
