Greatest Common Factor
We found the factors 438,193 . The biggest common factor number is the GCF number.
So the greatest common factor 438,193 is 1.
Lets's calculate LCM of 945,633
3 | 945, 633 |
315, 211 |
∴ So the LCM of the given numbers is 3 x 315 x 211 = 199395
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/199395
Therefore, the GCF of Fractions 438/945,193/633 is 1/199395
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 945,633 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(945,633) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(945,633) x common factors =3 x 1 = 3
LCM(945,633) = ( 945 × 633 ) / 3
LCM(945,633) = 598185 / 3
LCM(945,633) = 199395
