So the greatest common factor 986,765 is 17.
Lets's calculate LCM of 921,459
3 | 921, 459 |
307, 153 |
∴ So the LCM of the given numbers is 3 x 307 x 153 = 140913
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/140913
Therefore, the GCF of Fractions 986/921,765/459 is 17/140913
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 921,459 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(921,459) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(921,459) x common factors =3 x 1 = 3
LCM(921,459) = ( 921 × 459 ) / 3
LCM(921,459) = 422739 / 3
LCM(921,459) = 140913
