:1,3,13,23,39,69,299,897
Greatest Common Factor
We found the factors 30,405,897 . The biggest common factor number is the GCF number.
So the greatest common factor 30,405,897 is 3.
Lets's calculate LCM of 80,26,903
2 | 80, 26, 903 |
40, 13, 903 |
∴ So the LCM of the given numbers is 2 x 40 x 13 x 903 = 939120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/939120
Therefore, the GCF of Fractions 30/80,405/26,897/903 is 3/939120
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 80,26,903 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,26,903) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(80,26,903) x common factors =1 x 2 = 2
LCM(80,26,903) = ( 80 × 26 × 903 ) / 2
LCM(80,26,903) = 1878240 / 2
LCM(80,26,903) = 939120
