Greatest Common Factor
We found the factors 207,403 . The biggest common factor number is the GCF number.
So the greatest common factor 207,403 is 1.
Lets's calculate LCM of 921,177
3 | 921, 177 |
307, 59 |
∴ So the LCM of the given numbers is 3 x 307 x 59 = 54339
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/54339
Therefore, the GCF of Fractions 207/921,403/177 is 1/54339
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 921,177 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(921,177) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(921,177) x common factors =3 x 1 = 3
LCM(921,177) = ( 921 × 177 ) / 3
LCM(921,177) = 163017 / 3
LCM(921,177) = 54339
