Lets's calculate LCM of 492,903
3 | 492, 903 |
164, 301 |
∴ So the LCM of the given numbers is 3 x 164 x 301 = 148092
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/148092
Therefore, the GCF of Fractions 891/492,7139/903 is 11/148092
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 492,903 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(492,903) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(492,903) x common factors =3 x 1 = 3
LCM(492,903) = ( 492 × 903 ) / 3
LCM(492,903) = 444276 / 3
LCM(492,903) = 148092
