Greatest Common Factor
We found the factors 31,78,73,83 . The biggest common factor number is the GCF number.
So the greatest common factor 31,78,73,83 is 1.
Lets's calculate LCM of 75,80,54,459
2 | 75, 80, 54, 459 |
3 | 75, 40, 27, 459 |
3 | 25, 40, 9, 153 |
3 | 25, 40, 3, 51 |
5 | 25, 40, 1, 17 |
5, 8, 1, 17 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 5 x 5 x 8 x 1 x 17 = 183600
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/183600
Therefore, the GCF of Fractions 31/75,78/80,73/54,83/459 is 1/183600
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 75,80,54,459 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(75,80,54,459) = 1
common factors(in case of two or more numbers have common factors) = 810
GCF(75,80,54,459) x common factors =1 x 810 = 810
LCM(75,80,54,459) = ( 75 × 80 × 54 × 459 ) / 810
LCM(75,80,54,459) = 148716000 / 810
LCM(75,80,54,459) = 183600
