Greatest Common Factor
We found the factors 787,722,665 . The biggest common factor number is the GCF number.
So the greatest common factor 787,722,665 is 1.
Lets's calculate LCM of 384,351,542
2 | 384, 351, 542 |
3 | 192, 351, 271 |
64, 117, 271 |
∴ So the LCM of the given numbers is 2 x 3 x 64 x 117 x 271 = 12175488
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12175488
Therefore, the GCF of Fractions 787/384,722/351,665/542 is 1/12175488
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 384,351,542 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(384,351,542) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(384,351,542) x common factors =1 x 6 = 6
LCM(384,351,542) = ( 384 × 351 × 542 ) / 6
LCM(384,351,542) = 73052928 / 6
LCM(384,351,542) = 12175488
