Greatest Common Factor
We found the factors 459,8400 . The biggest common factor number is the GCF number.
So the greatest common factor 459,8400 is 3.
Lets's calculate LCM of 231,7497
3 | 231, 7497 |
7 | 77, 2499 |
11, 357 |
∴ So the LCM of the given numbers is 3 x 7 x 11 x 357 = 82467
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/82467
Therefore, the GCF of Fractions 459/231,8400/7497 is 3/82467
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 231,7497 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(231,7497) = 21
common factors(in case of two or more numbers have common factors) = 1
GCF(231,7497) x common factors =21 x 1 = 21
LCM(231,7497) = ( 231 × 7497 ) / 21
LCM(231,7497) = 1731807 / 21
LCM(231,7497) = 82467
